Abstract :
This paper presents a PWM strategy of matrix converters for minimizing input current harmonics. The PWM strategy which has only four commutations in all three phases during one control period is proposed. The PWM patterns for reducing the input current harmonics are indicated. The PWM pattern selection algorithm based on instantaneous effective value for minimizing the input current harmonics is derived. The effectiveness of the proposed PWM strategy has been verified by experiments.
