Abstract :
This paper proposes a three-phase, two-switch, buck converter that can operate with input power factor correction. The key features of the proposed converter are that a switch in it can operate with almost half the voltage stress of that in the standard three-phase, single-switch buck converter and with less current stress. In the paper, the operation of the converter is discussed and a detailed mathematical analysis is performed to determine its steady state characteristics. The results of the analysis are also used to design the converter using a procedure that is explained in detail. The feasibility of the proposed converter is confirmed with results obtained from an experimental prototype.
