Abstract

A new three-phase current type AC-to-DC power converter has been developed by the authors. This paper describes the principle of the circuit operation and the circuit configuration of the AC-to-DC power converter controlled by PWM. Simulation analyses of each waveform, such as AC and DC voltages and currents, are calculated by Euler´s method. The simulated values of the total power factor agreed with the measured values within the difference of 5.8% on the condition of full load, 10 kW. When the AC side voltage is unbalanced, it is found by simulation that the total harmonic distortion controlled by both feedforward control and AC side current feedback control (proportion gain, k₄=1) is restrained at only 38% compared with only feedforward control (k₄=0)
