Design and simulation an open loop AC chopper converter with an RL load with the approach of reducing the output and input total harmonic distortion

In this article an open loop AC chopper is designed and simulated. The load side of the converter consists of a resistance and an inductance. The aim of this paper is to achieve both an output with low total harmonic distortion and an input with low total harmonic distortion as a result a high power factor both in the output side of the converter and in the input side of the converter will be seen; therefore the power losses during the power transmission process will be decreased but the power quality parameters in the converter will be improved. There are two main control methods for switching the power electronic switches in this converter; open loop control method and closed loop control method. In this article open loop control method is considered.
