Application of AC Voltage Regulator with Chop-Control in Sine-Wave Regulator Equipments

The technique of single phase voltage regulator with chop-control is a new and high-performance technology.And this technique is more and more popular in the application of equipments with sine-wave voltage regulator.This paper adopts the topology of single phase voltage regulator with chop-control,introduces its principle,contrasts two controlling method,including the method of complementary control and the method the non-complementary control accompanied with detecting current.In addition to describing the theory and analyzing the control mode,some simulated results are provided to demonstrate the effectiveness of the proposed approach.
