Abstract

A new three-phase buck/boost/buckboost power factor correction rectifier is presented in this paper. For the converter, only two high-frequency switching actions exist in each sample period, and only one inductor is used. As a result, system efficiency can be improved. The commutation procedures are analyzed for the three modes, the controller design of the rectifier is discussed, and the output duty is assigned between switches according to different intervals of input voltage. Experiments are conducted to verify the effectiveness of the proposed rectifier.
