[sdiy] Snubber Capacitors

[Gergo Palatinszky]

Yep four... over each diode in the bridge ... and as many big capacitor X * 1000-4700uF you have after the bridge to smooth more the wave as many small cap (100nF) next to the big caps...

Hi,

In my BIG PSU (~10A) I used caps only (100nF or so)  ... might overkill to deal too much with it...

Hi,

I'm designing a power supply for my synth. I want to put snubber caps for the bridge rectifier on the PCB in case I find a need for them, but am not sure whether to have one across each diode, or just one across the bridge. Also sometimes a series RC circuit is used. Would it be best to include room for a resistor as well?



Regards,
Stewart.
