Abstract：The use of two-stage matrix converter(TSMC) in starter/generation system is investigated in this paper. In order to simplify the control strategy, three-phase-six-beat method is adopted when the motor starts. Considering the characteristic of TSMC and motor control strategy, two feasible methods are proposed when the motor starts and the features of the two methods are analyzed in this paper. Through the amendment of the modulation index timely, the regulation of output voltage can be realized. And the adjustable speed was implemented. The feasibility and effectiveness of the control strategy is validated by simulation and experimental results.
