Hi...
I have designed three smps using tinyswi tch - 4 family with different output power rating.
Each smps consits pi filters after the bridge diode. The pi filter consist two bulk capacitors and a single choke.
Now, I want to mege these three smps using a single bridge diode, and single pi filter.
Thus the connection will be bridge diode after that an electrolytic capacitor after that a choke after that agin a capacitor and the high voltage dc will be divided into three smps.
My question is, how can I choose the pi filter capacitors and the choke value?
