Finally, I could understand WHY we must NOT to use a Triac to drive DC current... Thanks a lot! Greetings from Argentina!❤

[@elewizard]

Glad it was helpful, keep watching other videos ❤️😊

[@ALEFILES]

@@elewizard Yes, you can bet I will! Thanks a lot for your wonderful videos, and the effort you put in each one! :)

[@Dailymailnewz]

@@elewizardI think a variable resister is far better to turn on the traic then the other little chip you mentioned...

[@rajanne2947]

Thanks! I understand triac clearly from your easy style of explaining! I was always confused about why triac can go ON but can't be turned OFF in DC use!

[@elewizard]

Glad it was helpful!😊

[@cedricpereira72]

Hello, nice video for beginners but there's a lot more to know when using triacs: - snubber networks for protection, - zero crossing switch to reduce electrical noise generation, - a lot of other things to consider 😁

[@elewizard]

That is right, I will cover more info about triacs in upcoming videos

[@kirkberryleo3307]

Well Im a beginner and for some reason couldn't wrap my head around a triac until this video..lol. now you got me scared lol

[@wackojacko1997]

You know, I think a 13 minute video is a great length, and this was just enough to whet my appetite. That other stuff sounds interesting, and it's fine to follow-up with additional videos of nice, bite-size lengths.

[@moeburn]

For years I have read about triacs, not really understood, and then forgotten everything I've read. Finally now I understand what they are!

[@elewizard]

Awesome, glad to hear that

a good explanation brother...thank you

[@elewizard]

You are welcome!

[@beyondfossil]

To turn on/off an AC appliance (like a light bulb), of course it's much simpler to just use a *relay* which can switch both AC and DC loads. The only real purpose of introducing a triac to a system is to clip the AC waveform and provide throttling which is a super useful function. That could have been made clear at the beginning of the video.

[@elewizard]

Thank you for expressing your opinion 👍

[@Mark-abc]

Great video. Why not just use a transistor to control the triac ?

[@elewizard]

It is possible to use a transistor. You may wonder it is possible to control the triac directly through microcontrollers GPIO. but us not safe. It is better to use optocouplers to isolate control section from the power section

[@mikepanchaud1]

Nice video! How would you quickly test a triac with a multimeter?

[@elewizard]

It is a good idea for a video 👍

[@kensmith5694]

Hook and ohm meter / diode checker between anodes. With the gate floating, the triac shouldn't fire. Trigger the triac It should have about one silicon diode's worth of drop when triggered. Depending on the triac and the meter, there may not be enough current to keep the triac triggered so connecting and disconnecting the gate may make it conduct and stop conducting. The main thing you are checking is that the triac isn't shorted and that its gate leg does something. The most common failure in a triac is they go shorted. The 2nd most failure is they blow open.

[@fardadma]

خیلی عالی بود ممنون من سعی کردم برای کنترل موتور کولر از ترایاک bt139-600E و moc3021 استفاده کنم اما به دلیل نزدیک بودن پایه های ترایاک هنگام روشن کردن موتور جرقه میزنه و باعث سوختگی در برد میشه. و عملا مدار قابل استفاده نیست. پیشنهادی برای حل این مشکل دارید ؟

[@sudheernorway]

How did you decide 100 ohm resistor between opto coupler and gate of triac?

[@mike-yp1uk]

That was awesome 👍

[@elewizard]

Glad you enjoyed it

[@rimmomos]

Thank you. I used an electronic contactor instead of a light bulb. It works well when it turns on, but it doesn't turn off. Why is that?

[@elewizard]

Was it a DC current you used? Because triacs can switch on DC but can't turn it off.

[@fardadma]

Hi, thats grate. Thank you. One question, I try to turn on and off a water based cooler motor ( an AC motor that start with 10A and continue with 2A load) with BTA-140 triac and moc3021, I also add a snubber circuit. every thing work fine and I can switch on and off the cooler at first, but when cooler working for about 20min BTA-140 getting hot and it did not disconnect the cooler switch(did not turn off the cooler) any more 😢. any idea or workaround about this issue ?

[@elewizard]

1-use a heatsink 2-use original parts I guess the triac you are using is fake

[@MUHAMMADYAWARIFRAHEEM]

Nice also make zero cross detector video 👍

[@elewizard]

Sure 👍

[@jamest.5001]

Can multiple be paralleled like MOSFETs for additional current capacity?

[@elewizard]

Yes, with some considerations, but is is not recommended. It is better to use a single triac with proper power 👍

[@mlekolak22]

Still it its recommended to connect light bulb between triac and neutral, beacuse if you connect it to phase wire you could get electrocuted when you accidentally touch connectors.

[@elewizard]

Yes, that point is a great one, however in the video, I was intended to demonstrate it from an electric and electronic point of view.

[@johnaweiss]

Since you're using optotriac to gate the large triac, does that mean your large triac is turning on and off every time the AC current changes direction? Why not just use an optoisolator?

[@elewizard]

Yes, that is right, actually the main triac is turning on/off 👍

[@johnaweiss]

@@elewizard Is it also true that the large triac would turn itself off every cycle, without any help from the small triac, and therefor the small triac's only job is turning on the large triac every cycle?

When you dim an halogen 100-watt light bulb with a dimmer, is the power consume always 100 watts?

[@elewizard]

No, power consumption will be decreased by dimming the bulb.

[@profesormates5973]

@@elewizard In the same proportion you reduce the light intensity?

[@lukejay]

[@VrishiSpin]

im trying to use a triac paired with an arduino to control the direction of an ac motor, how would i go about this?

[@elewizard]

Consider using a contactor

[@VrishiSpin]

@@elewizard so i would connect the pins that energize the contactor to the arduino, and wire up live wire to the motor through each side of the contactor, and that will allow me to control the turning on and off of the motor right. Also, how would i use this to change the direction of the motor

[@clueless_andy]

so basically if we try to use the triacs in DC applications, it is literally like using a thyristor and we lose the point of using a triac

[@elewizard]

Yes, exactly

[@eboy536]

How can dimming a incandescent bulb using Potentiometer isolated

[@elewizard]

In digital dimmers we use opto-couplers

[@eboy536]

@@elewizard but how is control circuitry for Potentiometer or rotary encoder

[@elewizard]

@@eboy536 maybe I could make video someday to answer your question

[@kensmith5694]

You can likely find a "light dimmer" circuit on line. The basic idea is to trigger the triac on only after some time has passed since the AC voltage went through zero. The old type of dimmers simply used a resistor and capacitor to make a delayed voltage and a diac to trip the triac when the voltage hits some value.

[@jensschroder8214]

Touch the Triac when the circuit is live? Crazy to touch Mains Voltage? 7:45 OK, you only have 120V AC and 170V peak. In Europe these are 240V AC and 340V peak. That bites you hard in the fingers! This can lead to cardiac arrhythmias or death. If you're lucky and just fall off a chair or ladder and break your bones. If things go badly, you can no longer pull your hand back and can't cut off the power. In Europe, the rule is to set it up safely, then take your fingers away and switch it on. Don't touch it never while it's hot ! Never or you'll regret it or it is to late !

[@elewizard]

Yeah, that is right 👍

Great, let's all put mains AC through a breadboard. No bad things will ever happen. Seriously, puting 120V AC through a breadboard is a very bad idea. Stay safe guys.

Yes it is dangerous, actually working with main voltage is dangerous in all cases
