looking forward to calculate snubber design

[deepakchikane]

Dear all..

i am new to electronics industry bt i aim to make a beautiful career in electronics coz electronics iz my first wife..!!

from last few days, i am trying to find sm answers bt bloody team mates coudnt helped me out..

please help me out to calculate snubber design..


looking forward to hearing you soon..!!

hv a nice day

it depend on the current ratings and voltages. generally in designs a resistor of 120 ohms (2 watt) with a .22 uf caps shall be seen.

plz some mathematical calculations..

 

[Magvitron]

please some inputs

 

[deepakchikane]

for transformers primary..

& dc to dc converter secondary...

voltages of 400v dc

??!! if you dnt give enough data, there wont be anyone helping you.

magviton...

i dnt have any example nw..

but if u give me one example from you design...

actually i m looking out to overcm to the overshoot into the primary of transformers...

Here's a great starting guide on snubber design:
**broken link removed**

In short, snubber design must always start with experimental measurements of the parasitic inductance/capacitance involved. After those are known, the snubber design is usually straightforward, though it may take some trial and error to get right.
