A novel operation strategy for single-to three-phase matrix converter

The single-to three-phase matrix converter is an array of controlled semiconductor switches that connects the single-phase source to the three-phase load directly. An analytic method, which is separation and link [1], is presented in this paper. Along with it, the operation strategy is obtained for the proposed matrix converter. To confirm the validity and feasibility of this strategy, the detailed analysis is provided for the matrix converter with a three-phase balanced resistance load. For the practical issue, a Permanent Magnet Synchronous Motor (PMSM) vector-controlled speed adjustable system is also designed. The obtained results show that the single-to three-phase matrix is of the strong capability of practical application in driving PMSM and the feasibility of the operation strategy is confirmed again.
