摘要

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 voltage is of great importance. Reducing the common voltage actively could be achieved by designing the proper modulation strategy a new modulation strategy with reduced common voltage in the context of double line-to-line voltage synthesis is proposed in this paper. It is based on the idea without employing zero vectors instead of the vectors which are opposite to the active vectors in space vector modulation. The modulation strategy is verified by the simulations finally.
