This paper presents a carrier-based modulation strategy for 3×1-modular matrix converters (MC) to achieve zero common mode voltage (CMV). A geometric method is introduced to determine the range of the modulation signals. Due to the nonzero CMV during the commutation time with the traditional four-step current-based commutation method, a modified four-step current-based commutation method is presented...
The double line-to-line voltage synthesis of matrix converter is based on the instantaneous value of the input line-to- line voltage. And the obvious advantage of this modulation strategy to automatically suppress the imbalance of the input voltage makes it excellent in the modulation strategy of the matrix converter. Considering the EMI issue in driver system based on matrix converter, common mode...
