摘要
Abstract
With the development of electric vehicles and wind power, PFC technology has been applied not only in the power supply equipment.. Because of the low efficiency and high loss of the conventional PFC converter at the state of the low input voltage, more and more researches have turned to the new bridgeless PFC converter. In this paper, a bridgeless Cuk PFC converter is studied. This bridgeless Cuk PFC converter not only retains the advantages of conventional Cuk PFC converters, but also has higher efficiency and higher power factor. With the discontinuous conduction mode (DCM) of the converter as an example, the working principle of the converter and the design of its parameters are analyzed in detail. At last, the comparison between the traditional Cuk PFC converter and the bridgeless Cuk PFC converter is done by MATLAB simulation, which verifies the correctness and effectiveness of the bridgeless Cuk PFC converter.关键词
