Design and Implementation of a New Three-Phase Two-Switch ZVS PFC DCM Boost Rectifier

M. Krishna Kumar, S. Prakash

Abstract: A new, three-phase, two-switch, power-factor correction (PFC) rectifier that can achieve less than 5% input current total harmonic distortion (THD) and features zero-voltage switching (ZVS) of all the switches over the entire input-voltage and load ranges is introduced. The proposed rectifier also offers automatic voltage balancing across the two output capacitors connected in series, which makes it possible to use downstream converters designed with lower voltage-rated component that offer better performance and are less expensive than their high-voltage-rated counterparts. In addition, the proposed rectifier also exhibits low common-mode EMI noise. The performance of the proposed rectifier was evaluated on prototype with a output that was designed to operate VL-L, RMS input-voltage range, and also simulation results are verified with the help of MATLAB/SIMULINK software.
