{992} How to increase SMPS output voltage

[@technicalcracker8926]

sir the video was very informative but plz make a practicle of duty cycle in relation with increasing and decreasing window for ampere and its advantages and disadvantages with respect to increasing or decreasing that voltage.

Very very informative and knowledgeable vedeo. Thank you so much. God bless you.

[@HaseebElectronics]

You are most welcome

[@john.84]

Hello, dear Haseeb You explain very well but if you increase the output voltage you must pay attention to the maximum voltage on the output capacitors. usually, those capacitors are 16v you better change those capacitors (for example 25v) Thanks for your informative videos GOD bless you

[@HaseebElectronics]

Yes, you are right it is very very important to reconsider the capacitor voltage rating with spare headroom of safe voltage

[@susantaatha6468]

Very nice information. Thank you sir

Very good teacher I want ask of the pcb you have tl431

[@CurioGene]

Hello Sir, I saw a video in which someone converting single supply smps into dual supply smps with reduced capacity... I like your explanation as you cover all aspects and its just for learning purpose however I want you to explain it in detail so that it should be proper working and usable... Thank you.

[@mahmoodh7767]

Thanks mr , very nice 👌👌👍👍🙏🙏

[@HaseebElectronics]

Most welcome

[@gauripartapshanker9197]

Informative vedeo. Thank u so much God bless you.

[@NisarAhmad-tf2pg]

Yes, Sir, we can, but we must also lower the current sense resistor on the high-voltage side FET/IGBT Driver and adjust the Duty cycle by changing the Capacitor and resistor of the Driver IC.

[@g4z-kb7ct]

Please do a follow-up video. For the next part of this video it would be interesting if you can use oscilloscope to measure the actual duty cycle before and after the modification to see exactly how much it has increased. Then put an adjustable load and find out the maximum current it can provide with the modification. Please do it in a future video. I think it would be better to use a 15V or 24V smps and modify it to lower voltage so that the smps is not stressed. But even so this modification is only +2.2V and the smps should be able to handle that without any issues.

[@rajkhumar001]

Really informative sir. Please explain us, how to track or read the circuit path or way in pcb. Because when we try to track lots of components between our way and I confused to track!. Please make one detailed video sir. Thank you.

How can I get the amperage back to normal? Can I increase the number of secondary windings?

[@HaseebElectronics]

if amperes are dropped after increasing the voltage then it is difficult to get full amperage, if we will try to increase then circuit will get in over stress. the MOSFET and all other primary side component will run in upper limit condition

[@padmaharsha]

Sir by increasing voltage will it cause any other parts to overload in the circuit witch will shorten the process supply lifespan. Can I increase up to 20 v

[@ranagaming165]

excellent work

Sir, i have smps 24 v, 10 amp . Its switching mosfet is short. After removing mosfet i found continuity on gate and source point on pcb (not on mosfet) which section can be faulty. Please help

[@ISO07ISO]

Son seğiştiridiğin direnç yerine ayarlı bir direnç koysak istediğimiz duty ayarı ile istediğimiz amper çıkışını alır mıyız? Son ayarlı drenç gibi bir direnç kullanırsak o bölgede iki tane ayarlı direnç olur ve biz yüksek voltaj istersek direnç değerini düşürürüz, yüksek amper istersek yükseltiriz. Böyle yapsak olur mu?

Circuit explanation

[@pauls7544]

Peace be with you always Sir, thank you for this, I need the opposite i.e to drop from 5v to 2.8v smps as I cannot find one. Will try it now, carefully. Perhaps for the viewer it would be better to modify a higher voltage smps like 18.5v to 14.2. I wonder would the increase in resistance change the effectiveness of the capacitor in this circuit. I don't get how the original duty cycle is determined but I probably was not in class the day you explained that in your clear and precise manner as always😊

[@g4z-kb7ct]

Use a 3.3v smps then adjust the voltage down to 2.8v using the potentiometer. No modification needed. Alternatively you can use small buck converter board available for $2 connected to the 5V output. It can take any voltage and output a lower voltage.

[@kennmossman8701]

at what amperage using 3 silicon power diodes in series will get close or use a series pass regulator [ywo resistors and a BJT transistor --- you can add a cap, Base to ground -- so it acts like a cap multiplier and reduces the spikes, noise, and ripple.

[@kennmossman8701]

PS put a bypass cap in parallel with a large cap

[@pauls7544]

@@g4z-kb7ct Thanks, I had the 5v smps in the correct dimensions and it's working fine so far🤞 I have buck convertors but they are max 2A with heatsink and circuit needed 2.5A all sorted👍

I can't increase the voltage to 40 volts. 12v psu.

[@HaseebElectronics]

No It is impossible to increase upto 40 volt. You need to rewind the transformer and rearrange the secondary side

Will you please upload the video with change gate drive transformer

If increasing output voltage is not advisable, then is it okay to decrease the output voltage ? What are the disadvantages of lowering the output voltage of SMPS, if any ?

Hi, I am a subscriber to your channel. I can't find the circuit diagram for the samsung tv LN46A750R1F. After I changed the main board for a used one I purchased from ebay, the tv keep turning on and off every few seconds. There is no image no sound only the sound of the relay and the stand by light allows to see what I have just described. Thank you in advance for your help.

>geri bildirim >>> pwm ic >>> sürücü mosfet >>> transformatör sargıları ve sargı kalınlıkları >>> hızlı diyot gücü >>> kondansatörler > geri bildirim>. saymadığım bir şey kalmadıysa, bunların hepsi önemli değil mi sevgili haseeb ? ic, transformatör, kondansatör yeterli seviyedeyse; ilk etapta yükseltme yapmak sakıncalı değildir bence !?!

it's not really good to increase the voltage. coz it requires to change number of turns which results into decreased current rating. turn on time will also change which is really dangerous
