SNUBBER CAPACITOR CALCULATION

The idea of a snubber is that the capacitor absorbs the inductive energy stored in the load at the moment the switch (photomos) opens, and its value must be large enough so that the voltage across it does not exceed the rating of the switch.
The resistor is there partly for damping and partly to make sure that the capacitor doesn't discharge instantly through the switch the next time it closes. Its resistance value and its power rating must be deduced from the worst-case conditions for both scenarios. The power rating is also related to how frequently the switch is going to be operating.

wow.... Great lecture .... Appriciate sir

Good
Go ahead..

[@SanjaySharma-pw6ww]

thanks for providing a valuable video.pls tell me how to measure the ringing frequency on dso.

The big problem is a good techer must be Pragmatic.build samples.but they dont do that.this work get their time.but teaching is god work.

secondary side RC network used in high frequency diode recovery stage

[@freedomisfood6966]

Hi my dude. I try for many week make trans pulse to isolate my switch ic and in ic side use 12v 3 amp to have a good pulse on the primary for trigger in half bridge 20 mosfet.please help.

[@hobby_plus]

I don't understand what you say.

[@freedomisfood6966]

You are a good enginer .i saw very indian engineer in youtube.but it is an problem .in formula all is excellent but in action all things gos differrent way.i months based formula in internet ,books want to make an fly back but cant.switch 🔥 or snuber 🔥 😢😢😢. I leav it.

[@hobby_plus]

just revers your fly back pole I think it will work.

[@benjaminbian2730]

why do you put the load in that way? Reduce impedance?

[@hobby_plus]

where I put the load?

[@freedomisfood6966]

Please show use how to calculate inductance of inductor in buck boost topology or at least its minimum

Thanks my doud

HELLO SIR .
What about R?

[@hobby_plus]

can you tell me in detail?

[@natsukifukawa6055]

​@@hobby_plusHe mean the resistor

[@hobby_plus]

ruclips.net/video/h8xYXuOR5ls/видео.html follow this video, you can get your answer.

[@freedomisfood6966]

Please

[@vishwanathbehere9066]

Very informative
But dont know the o/p RC purpose.

[@hobby_plus]

Please can you explain "the o/p RC purpose". what is that?

[@vishwanathbehere9066]

@@hobby_plus R and C connected in series between terminal 1& 2 . I cant understood the purpose of this ??

[@hobby_plus]

This is high frequency filter, vary affective protection for cosmic affect.

Please check this video ruclips.net/video/kA5G6VS9M1c/видео.html. Is it okay?
