A novel modulation strategy to minimize the number of commutation processes in the Matrix Converter

The applicability of reaching to higher switching frequency (f_sw ≥ 25 kHz) for the modulation of Matrix Converter (MC) is essential to reduce the size of reactive elements at both input and output filters of the MC. A higher switching frequency is limited due to the required number of commutation processes in a switching cycle period of the MC. To enable the MC to operate at a higher switching frequency, new modulation strategy is a potential approach. This new modulation strategy should minimize the number of commutation processes in each switching cycle period. This paper develops a novel modulation strategy that minimizes the number of commutations to half of the number of commutations required in a Symmetrical Space-Vector-Modulation (SSVM) method for the MC. Therefore, the switching frequency can be increased in comparison with that of the SSVM.
