Abstract :
A new AC-DC single-stage PWM full-bridge converter is proposed in the paper. The outstanding features of the converter are that it can operate with an excellent input power factor, and a DC bus voltage that is always less than 450 V and that has much less variation with line and load change than boost-type single-stage converters. In the paper, the operation of the converter is explained, its design is discussed, and experimental results that confirmed its feasibility are presented.
