3-Phase Modular PFC Converter for High Voltage Gain Applications

A new modular three phase topology is proposed for Power Factor Correction (PFC) that features high voltage gain. This proposed three phase converter consists of switched capacitor cell in each module. In the proposed topology, all components have voltage stress equal to half of the output voltage. This converter features modular structure, less voltage stress across the active components, high voltage gain, good power factor. Average current control is implemented to have unity power factor and low harmonic distortion. MATLAB/SIMULINK study has been carried out to ascertain the performance of the proposed converter.
