Abstract The usage of the two-stage matrix converter (TSMC) in the starter/generation system is investigated in this paper. Then a new generator/starter system based on TSMC (TSMC-S/G system) is constructed. Three-phase-six-beat modulation strategy is adopted when the system starts . The PWM modulation is used to regulate the current of TSMC. Considering the characteristics of the system, the effects of different PWM modulation modes on the bus current of TSMC, the safe commutation strategies, the torque ripple, and the voltage and the current of the non-conducting phase are analyzed in detail. The characteristics of various modulation modes are also studied, and the optimized modulation strategy is proposed to finalize the most suitable modulation mode for TSMC-S/G system at starting. The feasibility and effectiveness of the control strategy are validated by simulations and experimental results.
