The charging inverter improves the system efficiency and controllability. Their applications

however

increase the harmonic distortion level of the input current. This paper analyses the relationship between the power factor and input current distortion of the inverter power source. A three-phase configuration of a new power factor correct circuit that makes use of continuou sinput current is suggested. Continuous sinusoidal current input is achieved by the average current mode control technique. The theoretical analysis is verified with digitally simulated results. The selected experimental results from labor atory prototype rated at a 5kW which demonstrates the three-phase power factor correct circuit operation are also presented.
