This paper presents a PWM strategy for minimizing the output voltage harmonics of matrix converters. The authors previously proposed a PWM strategy in this strategy, the number of commutations in all three phases during the control period can be reduced to four. In this paper, by using the detected output current values for calculating the duty cycles, the continuously varying duty cycles for a control...
This paper presents a control scheme of matrix converters for reducing the number of commutations. The proposed control scheme is based on the direct AC/AC conversion approach and the carrier-based PWM control to obtain the constant switching frequency. The feature of the proposed control scheme is the reduction of both the number of the commutations and the output voltage harmonics. The effectiveness...
