This paper presents the analysis of high power factor three-phase AC-DC current injection hybrid resonant converter. The series-parallel (hybrid) configuration of the resonant converter using current injection technique is the key concept of this paper, which is realized by injecting the highfrequency resonant current to the diode-bridge rectifier. Featuring a high-power factor operation, the circuit offers low total harmonics distortion (THD) level of the input current waveforms, hence increase the quality of the power supply system. The analysis of the proposed converter is first carried out using MATLAB to investigate the feasibility and the effectiveness of the theoretical analysis. A prototype of a 1kW three-phase AC-DC current injection hybrid resonant converter (CIHRC) is then developed to support the simulation analysis. Selected simulation and experimental results are presented to verify the feasibility and the effectiveness of the theoretical analysis of the proposed converter.Downloads
