magnitude of spike in full brdge rectifier with snubber
hello all.
I designed a full bridge smps, with secondary full bridge rectifier. The circuit work in hard switching mode.
The schematic is as follows
The circuit present a big spikes. I design snubber for solve this.
Secondary voltage without snubbers
and secondary voltage with snubber
This is a RC snubber with values R= 150 ohms and C=680pF
I try many combinations of resistors, and the spike is always present(although it is smaller).
Is it normal that the spike never disappears?
there some other method, for reduce the spike?
thanks and regards
