Duality of PWM strategies between current and voltage source AC/DC converters for suppressing DC ripple

This paper presents duality of PWM (Pulse Width Modulation) strategies for reducing the DC ripples between current and voltage source AC/DC converters. The authors propose the PWM strategy of a voltage source converter for reducing the DC current ripples using the PWM strategy of a current source converter. The validity of the duality of the PWM strategies between current and voltage source converters is verified by experiments.
