Abstract

This paper proposes an AC Chopper based DC power supply for specific DC voltage ranges. AC chopper is attached to the input side of PFC to generate specific ranges of DC voltage which are not available with PFC itself alone. The input power factor of the proposed DC power supply is proportional to that of PFC. Performance of the proposed power supply was verified by carrying out simulations.
