Switching power supply for Viper22A

[@AshokNaik-jg7bw]

You are one of the best SMPS expert. God bless you.

[@Den_Electro_channel]

Thanks a lot!

Thank you :)

Splendid and to the smallest detail. You the best. Big up here in South Africa.

[@ezeoluchukwu5104]

more strength to you keep good work going. I can say u are one of the best i have ever seen on the internet that is doing wonderfully well in explaining power Electronics very very well. Indeed, where u beat others is that u explain with the illustration of showing the turns of ur winding,

[@Den_Electro_channel]

And thank you for watching. I think the transformer is the most difficult part, and some bloggers don’t show how to make it well, so I’m trying to do it in more detail so as not to repeat their mistakes.

With this comrade and Viper chip you are really spoiling us. Please consider designing a dual rail +/-12 or 15v with 5v DC supply.

[@supersilve]

Very good explanation and good work. Good job you did with transformer winding.

[@Den_Electro_channel]

Thanks!

[@Sahilkhan-jd5fz]

I have recently subscribed your channel to learn about making power supply thx for making such videos.

[@Den_Electro_channel]

thanks for subscribing!

Hi sir I am bharat kuhikar frome India in nagpur .you are grate sir and verry nice experience and explanation

[@Den_Electro_channel]

Thank you for watching bharat kuhikar!

[@michaelbenard6758]

Would you please do a full 20min tutorial about transformer and inductors with all their calculations including choosing best cores and what frequency is suitable depending on the core(ferrite, iron powder etc) and application.

[@Den_Electro_channel]

Unfortunately, it will take a lot of time to prepare this video. It will be released in the future, but I can’t tell you the exact date.

[@bazrazin1]

really talented for winding your own transformer with air gap adjustment, also can you show smps with other commonly available chips or power transistors like 13003, i wanted to make a dual 5v & 12v/2A each.

[@Den_Electro_channel]

In the future, I will make power supplies based on transistors and other microcircuits

[@Yorumcu63]

Great video

[@Den_Electro_channel]

Thanks

[@suryasen4723]

Good analysis 👌

Thank you

Nice video

[@electronic-ebox6403]

hi you presented this very nicely. i have issue with same IC. my circuit has little bit difference. i am using extra transistor along with TL431. my issue is with short circuit protection. after 800mA current viper22a blast. also do you expalain about electrical load you use in every video?

[@Den_Electro_channel]

hi there is a video on how to make an electronic load, but unfortunately I haven’t translated it yet

Nice

Thank you

[@jboy4real]

How did you choose the value of the EMI filter inductor on the AC line side

[@Den_Electro_channel]

It is necessary to look at the cross section of the wire wound on the filter so that it does not heat up from the passing current. You can also calculate the required inductance of the inductor based on the frequency at which the power supply operates. But there are very complex calculations, I do not use them. Therefore, I always look only at the cross section of the wire. You seem to work for some electronics company. If you know an easy way, please let me know.

[@ncuzdvarga4918]

Hi, how to make it with CT output? thanks

[@michaelbenard6758]

Bro you are talented.!! 👍🏽

[@Den_Electro_channel]

Thank you

[@morgan0gaming]

Good

[@electronic-ebox6403]

hi how do you calculate the winding required for transformer? i am little bit confused.

[@Den_Electro_channel]

There is such a program as VIPer Design Software. there you can calculate the transformer for power supplies on the viper chip

[@electronic-ebox6403]

@@Den_Electro_channel thanks for replying. But what about other ic you used such as AP series or UC38 series ic?

[@Den_Electro_channel]

using the program "flyback 8.1"

[@MYMusic-l5l]

please helpme, instead of getting 12v dc ouput, my PSU getting 45v output. how to regulate the output?

[@MYMusic-l5l]

how do you figuring out the TL431 to regulate the ouput?

[@Den_Electro_channel]

If everything is correct, then the voltage should be 12 volts. And if you have 45 at the output, then you have a mistake somewhere in the circuit, or the parts are faulty. Are you sure the TL431 is working? If you connect something incorrectly, it is easy to burn it. How TL431 changes the voltage can be understood here: kzbin.info/www/bejne/g3SVpIibrd-frZY

[@Danar_Khafidyan]

i made it, but the voltage is too high may target is 12v. beside that the voltage is fluctuating.can you help me how to adjust the output voltage

[@Den_Electro_channel]

Does the voltage fluctuate under or without load?
