Improving Voltage Transfer Ratio of Matrix Converter Employing Single-Mode and Two-Mode Overmodulation Technology

The single-mode overmodulation strategy of matrix converter is put forward for the lower voltage transfer ratio. Single-mode overmodulation strategy and its effect on increasing voltage transfer ratio are analyzed theoretically, and the simulation model of the strategy is set up. Theoretical analysis and simulation results show that the proposed strategy can make the voltage transfer ratio rise to 0.95 from 0.866. Compared with matrix converter two-mode overmodulation technology, the same purpose can be achieved by single-mode overmodulation, and the single-mode one is simpler and easier to control real-time, and it has theoretical research value and application prospects.
