How To Convert DC to AC | Direct current Inverting | 3D Animation

#dctoacinverter converter #dctoac #directcurrent #alternating_current #electronic
In this video, we'll be discussing how to convert DC to AC. We'll be using a 3D animation to illustrate the concepts.
If you're ever in a situation where you need to convert DC to AC, then this video is for you! By the end of this video, you'll be able to understand how to rectify DC, and use this knowledge to solve practical problems. So make sure to watch it!
There are two forms of electricity - alternating current (AC) and direct current (DC).
DC is a linear type of electrical current - it moves in a straight line/flows in one direction. This current moves from the positive pole to the negative pole, while electrons produce electricity while moving from negative to positive.
For DC, the positive and negative poles always remain the same.
AC is a current that constantly changes its flow between positive and negative terminals. This means that electrons also change their flow, following the negative to positive end as the polarity changes.
The speed at which AC changes polarity and completes several cycles in one second is called frequency, and it is measured in Hertz (Hz).
the conversion of DC voltage to AC voltage is a common problem. In any circuit, we can observe that if we design a circuit that takes the AC input and gives DC output. But, if we want to change the circuit from DC to AC, a DC to AC converter circuit is used. The inverter (converter) is frequently required in the circuits like where DC to AC conversion is not possible. So, an inverter circuit is employed for converting the DC to AC converter.
PS : Dear friends, the ammeter connection shown in this video is totally misleading. You should connect an ammeter in series manner with the circuit, I was completely messed that up. But it will not affect the core idea of how to convert DC to AC. Ill upload the corrected videos ASAP.

[@pubuduweerakoon7174]

Your honesty is appreciated !

[@sandeepkumarsah6766]

Yes

[@soumithraanand6377]

Sir I have a doubt ...will the current produced be enough for a electromagnetic induction ...as I'm trying a project on mutual induction like the one in transformers ...but a little simple one with 2 coils placed one over the other

[@soumithraanand6377]

I would really appreciate your help🙏🏻

[@ClosestNearUtopia]

Next to that you cant convert dc to ac in the first place.. since ac is a pure sinus.. You can generate a pulsing artificial sinus tough.. You do convert ac to dc yes. Next to that, that modified sine wave was btw the simplest of its form, and is more an example of a pwm signal.. A good ac generation consist of multiple square-waves where each one follows the actual sinus, so its not just two pulses of dc like you described anyway it consist of a few dozen of those all having a small intervall, having all their own amplitude related to the momentary voltage.

[@NightWear21]

Been studying electronics for about a decade on and off. The good thing is, things haven't changed much. Sure, we have better memory and faster more complex chips. but the gist of it hasn't changed in hundreds of yrs. I still find myself exploring diode functions, resistor functions, ect ect. Well made video. Thx.

[@watchinyoutube8919]

For the most part the principals of electronics really aren't too susceptible to change as the foundations are based on physics

[@NickDude69]

We need more people like this. This is a helpful instruction. I am 12 and my father is an electric engineerer and we are both very intimated.

[@sacredwillyslicer]

bro plz use proper english because intimated means you want to reproduce

[@Ghoost73]

Hello! Ampere meters are NEVER connected in parallel with the consumer! (time: 1:44 --> ) You can draw the same diagram by measuring the tension :)

[@andrewgjennings]

He knows, he mentioned that in his pinned comment

[@Filipx87page]

The dead time (Modified square wave) is introduced not only for a better approximation of the Sine wave, but also for the protection of the transistors as they could short out when toggled. Very nice video tutorial. 👍

[@Profmad]

Thank you

[@mrchin7562]

That's interesting... What application is this?

[@sumedh.homeoneSumedh]

thanks a lot for your efforts! You have good skill to teach a hard topic in an easy manner!

[@stephenjacks8196]

Long AC power lines have more resistance (c.f. skin effect) but also have impedance and radiate energy (an effective antenna for 60Hz is 750 miles. The Pacific Intertie is a 500,000 volt DC line from Bonneville Dam in Washington carrying 1500 Megawatts to Los Angeles. The conversion to AC was originally using raquetball court sized Mercury Thyratrons and a field of inductors and capacitors.

[@siglavikingkearns8108]

I worked for Manitoba Hydro (technician, not engineer) just after they built their first DC system using Mercury Arc Valves. I was still there when they switched over to Thyristors. Big job, interesting stuff, although some of it pretty complex for a tech to understand.

[@alamelu9996]

Sir...your lectures are awesome 👍🤩 Mind-blowing...need more videos about electronic and electronics...I am a EEE student

[@Profmad]

I will try my best

[@sumitnsinha]

Wow. Great explanation. It clarified how few electronic devices work.

[@Profmad]

Glad it was helpful!

[@rahulmenon12]

Thank You! You have no idea how much that helped.

[@Profmad]

Glad to hear it!

[@berryj.greene7090]

Well that Ammeter really ought to be a voltmeter. The snag is that we want to use the terms "Alternating" and "Direct" Current. It always seems worth the while to show the origin of this with a magnet spinning near a coil. The speed of the motion gives the frequency. Its the voltage output polarity and extent of it during the cycle that is so informative. So is the notion that without the changes it won't work! Now with that done we can move on to describe that in basic circuits - say lamps and heaters - it won't matter. Then we have the spin off that is induction which allows us to step the voltage up or down (transform) and is is so useful. NOW we can embrace conversion from ac to DC and vice-versa.

[@bisdakmillennial]

Your videos make our life easier. Thanks.

[@tatcathudientu]

Lol in 2024 and this is the first time I really understand. What's the H Bridge 😮 Listening the DC to AC for more than 10 years but never understand how it works 😅 Thanks you bro !

[@keithminchin1817]

👍🏻 Well done. The peak to peak voltage (amplitude) will be greater than the RMS value. Sinusoidal PWM control of the H-Bridge is worth a mention.

[@abubkerali4798]

Great video ! Well explained, . Very good job. I have subscribed to your channel.

[@Profmad]

Awesome, thank you!

[@ronmorey1246]

I was taught in the military which teaches electron flow, so every once in a while I mix it up with the positive to negative flow. It is a hassle sometimes.

[@aliazzahid6311]

Nice presentation sir. Looking forward to enjoying upcoming videos.

[@Profmad]

Thank you , and keep watching.

[@pomme4682]

The conventional direction of electric current was originally taken to be from the positive pole to the negative pole of a battery through the external circuit. This system is still used, and causes no problems, even though we now know the electric current is caused by electrons drifting from the negative to the positive pole. Incidentally the speed of the electrons is so slow that, for example, a flashlight battery will probably run down before an electron has gone around the circuit even once.

[@Profmad]

Thank you for sharing this.

[@WaterproofSoap]

A Lumped Element Model is used to describe circuit schematics and electron "flow" The truth is, it's the movement of the EM fields that brings the fun to the party.....but parsing that out each time troubleshooting takes place would mean nothing would get done. "Electron flow" is a lumped element type of shorthand.

[@andrewgjennings]

​@@WaterproofSoapagreed, I think actual electron flow is something like 1 foot per hour, or some ridiculously slow travel time.

[@stayblessed4898]

Crazy how that impatient freestyle go so hard!! Simple beat, nothing extraordinary🤷🏻‍♂️ it’s DRAKEOS, word Play so dangerous 🤟🏼✊🏼

[@davidshaw3303]

Great video. Please don't forget that most of the world is 220/240V 50Hz, (and US houses are supplied with 240V).😊

[@crivete7686]

Should the Amplitude not be ~170V? (120V * √2) as far as I know they have 120V RMS in america.

[@endurofan9854]

i guess its more posible to use volt meter rather than ammeter on that parallel connection, it can also show positive and negative reading if its only to show the polarity

[@cheunruthai4516]

ขอบคุณครับ..ที่ฟื้นความจำจากตำราเรียน ในวิชา อีเล็คโทรนิค ตอนการสร้างกระแสคลื่นรูปฟันเรื่อย ซอทูช ในวงจรภาคกวาดเส้น ทางแนวตั้ง และทางแนวนอนในระบบ ทีวี สมัยก่อน ตั้งแต่ ทีวีขาวดำ แบบหลอดสูญญากาศ...

[@arnelsantamaria1486]

Accurate diagram showing so far it is very easy to understand.👍🙂Thank u Sir.

[@tomchiaveagto6340]

just a heads up, the voltage of a wall outlet is actually 120v rms so the amplitude of the sine wave would be closer to 170v, not 120v like you said in the video

[@indridcold8433]

I always made a colpitts oscillator and attach it to a current amplifier. It makes for a very clean oscillator.

[@reflix2983]

Greetings, I'm impressed by the history lesson of how our ancestors believed "electrons flowed from positive to negative"; and since apparently everyone agrees that is wrong, but embraces the error by giving it a name - is such a disservice to anyone who wants a proper education. From an engineering standpoint, understanding current flow through any electronic circuit is paramount to troubleshooting and circuit design. Historically, some of our 'other' ancestors believed the sun orbited the Earth, and when it was proved otherwise, (after much consternation), they relented. Others believed the world was flat. . . but I digress. On this planet those that only operate an electronic device know "how"; engineers know "why". What planet are you from...?

[@Profmad]

Appreciate your comment.

[@bingosunnoon9341]

This comment is not helpful at all. There is nothing wrong with the way current flow is described.

[@lukschs1]

Encontré Oro, Mil gracias , ahora comprendo un poco más el Panorama xD

[@Profmad]

Nice to hear that.

[@jagc1969]

[@Profmad]

Awesome, thank you!

[@mxr572]

I believe the inventor of the rectifier tube was Rogers in Toronto, Canada.

[@mersoneusebio5523]

Very good explanation, I liked it!

[@Profmad]

Glad to hear that!

[@pardeepsingh-iv6pu]

Thanks sir for your informational video

[@Profmad]

Thank you.

[@98.y]

Thanks from iraq 🇮🇶 😘

[@dwaipayandutta5816]

Good and knowledgeable video..I have some questions and queries related to this video. 1. How much positive voltage we have to apply to base for current to flow through collector and emitter? 2. How we can control the current flow between collector and emitter by applying voltage or pulse to the base? I am very interested at knowledgeable video with good explanation so I am looking for to you kind, fast and fruitful response.

[@Profmad]

1. Since we are working with high power applications, normally we use IGBT (Insulated Gate Bipolar Transistor)s for switching purpose. IGBT's applied VGE (gate-emitter voltage) should be at least 14 V (preferably 15 V). Its better to check the data sheet of the component. . 2. I have made another video to explain how does the transistor work. kzbin.info/www/bejne/m4uklpSJoMx8gpI I hope this will help you.

[@khinmaungtun411]

THANKS FOR YOUR SHARING SIR

[@Profmad]

Most welcome

[@mohammady4477]

It is very good and exellent

[@Profmad]

Thank you

[@alexserdukov1595]

You’ve shown ammeter connection wrongly (at 1:54) It should be connected serially, not parallel. Alternatively an measurement shunt resistor may be connected serially with ammeter connected parallel to it, but not to the load

[@Profmad]

That's correct. There is a mistake there. Thank you for the comment.

[@adelmomontero3554]

It would be good if you guys toned down that annoying music so that it's easier to follow your explanation.

[@KGopidas]

What about conversion losses, does it defy kse of thrtmodynamics?

[@abdulkarimtalb9178]

Thankful good information

[@shafiularman7703]

Using PWM inverters, better sinusoidal waves can be acheived

[@Profmad]

Yeah, its one method.

[@hhemasi9849]

So what is the difference between a simple switch and an igbt? As you say still igbt need a swiching to change the current

[@sohailjanjua123]

Hi, I Like your video. Thanks

[@Profmad]

Hey, thanks

[@curiosity2learn376]

07:56 I think diodes should be in series not in parallel with IGBTs.

[@exabyte2402]

Good animation, new suscription.

[@Profmad]

Awesome, thank you!

[@andrewgjennings]

Awesome video. You explained the conventional and present means to describe current flow, current flow in general, and the different kinds of AC wave forms. These topics are rarely covered in these kinds of discussions, well done. I would like to have seen how capacitors are used to create the offset since wave, I suspect that the result is truer to sinusoidal waves than shown.

[@drtnrao57]

Good video thanks.

[@dyriten]

very good video and very well explained

[@Profmad]

Glad it was helpful!

[@gideonvella6361]

Hi is the are any dc to aç converter 120vdc to 120vac? Do you have any brand you can recommend ?

[@allanwrobel6607]

But you haven’t explained how the pure sine wave is formed. The curcuity required.

[@industrialwithpraveen7947]

Kya igbt lagane se transformer ki jarurat nahi hogi

[@vinaykandari9910]

Thank you bro

[@Syed_vlogs_YT]

Sorry to interrupt,not transistors but MOSFETS are the fastest switches.

[@baljeetin581]

So good to see you ❤

[@KGopidas]

What is the efficiency if thr conversion?

[@wazirali1656]

Excellent

Luar biasa from indonesia

[@Profmad]

Thank you.

[@jozsiolah1435]

Similar to those IC transistors, used in DC screwdrivers to adjust the RPM. These black ICs are connected to stronger ones, to provide SIN current, but not all devices support that. UPS devices are GPS powered, to ensure safety to turn on electricity in time, if prepaid by the owner. Insurance companies need that, to avoid data loss of the owner. UPS is also needed to download the Media Center updates for Vista, Win7. It’s also needed to turn on the performance mode of a PC, when drained in BIOS, but the timeout of the UPS has to be set to maximum. When a UPS is monitored by a satellite company, they fire a nuclear beam to the black IC transistor, to weaken its performance. Now on, XP and better operating systems won’t be supported, because the power good signal is bad. Same with screwdrivers, when misused, the IC is attacked by the laser, and will heat up dramatically, the throttle can’t be adjusted.

Thanks!

[@periyasamyvanitha3604]

Could please explain howmuch voltage should be apply to the gate terminal

[@Reaktanzkreis]

3:30 Worldwide 230V dominates. In my home 230/400V at 59Hz is standard.

[@Reaktanzkreis]

50 Hz not 59

[@Profmad]

Yeah , actually there is a interesting story behind the selection of 50 Hz. I hope to make a video about that near future.

[@counterleo]

Great video but you need to upgrade your switches to IGBT so you can generate more frames per second :D

[@Profmad]

Ok, thanks

[@МаксимКасимов-д5е]

Thank you!

[@WORDversesWORLD]

It's super easy to convert DC to AC, you just alternate it, sorry couldn't resist.

[@Moti.122]

I say to from Bangladesh ❤

[@ligyrophobia]

it should have been said that transistors can be opened and closed using a multivibrator

[@madtscientist8853]

If you have a 1H coil and a 1F capacitor and pulse it at the right frequency. You will not have heat and will get long voltage out of it.

[@gulashonu]

"Damn nature, you scary!"

[@shahzaiburrehman4908]

Best information thanks 👍

[@Profmad]

Thanks for liking

[@cooly1765]

sorry to say but I think at 3:20 your "Complex Waveform" isn't AC. Alternating current must have equally sized (not formed) areas above and under the t-axis.

[@amirhosain6026]

Many many thanks

[@Profmad]

Most welcome

[@VelocityWIS]

Thanks man you helped me alot 😊

[@Profmad]

Glad to hear it!

[@patrickbrady447]

Thank you for this Vidio, but the AMP meter was not wired correctly. All the current in the circuit should flow throught the Amp meter.

[@aurora_12349]

In ac does live and neutral wire interchange?

[@johannodendaal7220]

Hi @Provmad, where can i find a arduino bpard to build this cercuit at home?

[@johannodendaal7220]

I am learning for electrision but want to expand my u derstanding of electronics

[@sagarrawat7203]

We can't measure current in parallel however voltage does

[@G1ZQCArtwork]

Current doesn't flow. Electrons flow in the form of Voltage. Current is the by product of work done by the load. Remove the load and no current can be measured. It does not flow in a circuit, it manifests itself as wasted energy in the wires due to the resistance. I do wish people could get this simple fact right.

[@Haithemenglish]

Ok if we suppose that electricity goes from - to + . Why when you do the switch in the side of the - side it burns the light . I think that elictricity follow from + to - that is why when we do it in the side of the + side it works and does not burn the light because we stop the fllow of electricity

[@elosha6509]

This is a very good video but at home there is mostly 50Hz and not 60 just a little corection

[@yedemon]

Emm.... not as much as i expected... I expect to seen different ways of reversal, or is it the only way?

[@Profmad]

There are other ways to make alternating current flow. I'm hoping to make videos about those soon.

[@yedemon]

@@Profmad Thx~~ that's great~~

[@mohammadmustafa722]

Nice explanation......can u explain the pure sine wave ckt

[@Profmad]

As soon as possible

[@sureshkumar-ux2nq]

Wow

[@iEveryMemes]

Alternating current has two terminals: Line and Neutral. Additional knowledge: "Line is the terminal with running light. The Neutral terminal has no running light. to provide complete power supply"

[@aubreypage3994]

You do not show the Amp Meters connected correctly (in series with the circuit).

[@Profmad]

It was one of my terrible mistake. I didn't notice it until this was publish. Sorry for the inconvenience.

[@rabari1994]

Can i find the pure sine wave from the function generators?

[@Profmad]

Yes you can, but it depends on the function generator model.

[@deepakkumardas6598]

The ammeter is always connected in series because it is low resistance

[@lusoclement3787]

no dude, its connected in series with the load because its measuring the flow of current that is coming in the load, by connecting it in parallel, you measure a different flow

[@rekiaouhaji4776]

ممتاز

[@jeremy_prl8439]

I'm not an expert in electronics, I just have basis and I'm an amateur but at 1:49 you show a DC circuit with an amperemeter in parallel but isn't it supposed to be in series for it to work ?

[@Profmad]

yes that's correct. There is a mistake there.

[@venkatbabu186]

A variable induction. Variable capacitance is voltage. To store voltage you use a variable capacitor on the way. Work in Velocity spin. Two d to three d. How do you mathematically prove that only two d and three d exist.

[@thrilokachandran.3693]

When transform A C voltage into D C voltage, it is called CONVERSION The device we used is Converter . But when transform DC voltage into AC voltage, is called INVERSION The device we used is called INVERTOR .

[@MohammadAlabbas-u8z]

Now, the transistors turn on as the positive current flow for example in transistor 1 and 3. How can the transistor 2 and 4 know that it is their turn to turn on

[@deang5622]

You design some sequencing electronics!

[@dharveyftw7349]

You can use 2 comparators. The + input of the comparitors can have a triangular signal input from a signal generator (which can be done using a 555 timer), and the - input of the comparator can have a sinewave signal generator (which can also be done with 555 timer). The switches only turn on depending on the cycle of the input AC signal.

[@DjTatty]

AC and DC difference's are, AC is switched on and off 50 times a second, or 50 cycles = Hz and DC is not, it's direct. Electric is electric, it's all the same stuff. You can only switch it off = 0, or switch it on = 1, the same as a computer works 1's and 0's and which the power symbol represents. Both need a positive and negative flow to work. If electrons exist and flow through cables, then how does wireless induction work? everything is fields, you find it easier to understand then. Think, water, ice and steam, then think, electricity, magnetism, dielectric. ther all the same thing, in different states.

[@giritharanbalamurugan9598]
