Abstract :
A new AC-DC single-stage, buck-boost, 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 with and a dc bus voltage that is less than 450 V. In the paper, the operation of the converter is discussed in detail, its steady-state characteristics are examined, and a design procedure is developed. The feasibility of the converter is confirmed with experimental results obtained from a prototype converter.
