Abstract

This paper presents a novel buck type AC-DC converter having high power efficiency, high power factor, simple control strategy and rugged overload protection. In this AC-DC converter, the power factor and harmonic distortions are improved by using sine weighted PWM technique and line filter. Thyristors are used as switching devices in the semicontrolled converter due to its low cost and protection is made simple by the use of semiconductor HRC fuse. The scheme has been simulated using SABER and experiments are conducted to verify its operation
