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...???Capture11.JPG
