Thanks for updating me G' ,
meanwhile an electrical engineer friend and colleague gave me some horrific facts about my powersupply.
1. For the capacitance(25000uF 150V) I am using the initial surge current would go upto 1kiloamps.
2. The bridge bkpc 5010 has a surge current handling capacity of 400 amps, beyond which the bridge will blow, like it did in my case.
3. He calculated that the bridge can take upto 11000uF capacitance at 110V.
3. The capacitance might burst in use bcos is just 40V above supply voltage.
4.he wasn't sure why the 8 amps fuse blew near the UHU servo and asked me to run the motor again in the lower PS and confirm if mosfet have survived.
well he filled up a full sheet with calculations and I think he is correct, he wanted me to use some sort of pi filter which he would design with a new powersupply.
I have asked him to design supplies individually for each motor so that I can switch on each one individually? I donno if I am doing right or wrong.........
then I just mentioned to him that design the best economical solution and he wasn't sure if a single PS would be economical or separate ones?
What ever the case I am looking again at around 200USD (8000INR) + investment on this.
hope some one else has better ideas!
