Abstract

This paper presents a direct AC/AC bi-directional power converter that can convert 220 V mains voltage to 110 V or vice versa in a single power conversion stage. The proposed converter makes use of four quadrant switches and high frequency PWM control to accomplish the desired voltage conversion at low cost and high power density. Due to the inherent low current distortion feature, the proposed power converter automatically provides a simple solution to reduce harmonic pollution of power supply. The operating principles of this converter are described. Simulation and experimental results of the converter have confirmed the successful operation of the converter
