Auto Transformer voltage Taping points are ( 220,270,320,370,420,470,520,570,620,670, & 720 volts) and current rating is 16.5A.
Power supply requirements are max 700V output, minimum 200V output, at constant 16.5A current.
I have used choke input LC LPF and simple transformer in the proteus image attached.
Kindly someone guide me in designing 2nd order LC LPF for above power supply, especially L1,C1 and RL values required...???

 

An autotransformer has no mains isolation, so is not suitable for use in such a power supply.

Thanks but I don't have any other option,as I pointed out the same thing with the Boss and he said just go with it as we have no budget for isolation transformer.

 

we have no budget for isolation transformer.

So then hope you have adequate insurance coverage for wrongful death from electrocution.
