Abstract

Two AC-DC PWM full-bridge converters that can shape the input current to improve input power factor while performing dc-dc conversion are investigated in this paper Both converters are simple in that they are similar to the standard PWM full-bridge converter with a diode rectifier/LC low-pass filter input, and both can operate with a simple method of PWM control. In the paper, the operation of the converters is explained and their steady-state characteristics are discussed. The feasibility of the converters and their ability to meet EN61000-3-2 Class D standards for electrical equipment are shown with results obtained from experimental prototypes The performance of both converters in terms of dc bus voltage level, input power factor and efficiency is compared and discussed.
