The conventional PWM scheme of the three-phase current source converter is much complicated compared with that of the three-phase voltage source type converter. This paper presents a simple PWM scheme for three-phase current source PWM PFC rectifier. This PWM scheme has been obtained through a study on the duality between three-phase PWM converters of the voltage source type and the current source type. Thus, the PWM scheme of the three-phase voltage source type PWM converter is reviewed first. Then, the simple PWM scheme of the three-phase current source converter is discussed by referring the discussion of the three-phase voltage source PWM converter. The validity of the theory is confirmed through experimental results obtained from a setups of the three-phase current source type PFC rectifier.
