摘　　要：将双级式矩阵变换器(TSMC)引入起动/发电系统,构成基于TSMC的新型起发系统(TSMC-S/G系统)。系统起动时,为减小控制复杂度,电机采用三相六拍控制策略。针对电机控制策略以及TSMC的结构特点,提出了两种可行的TSMC起动调制策略,并分别分析了这两种调制策略的特点以及应用场合,推导了TSMC直流母线电流与开关函数间的数学关系。以占空比作为系统闭环调节的中间变量,及时调整TSMC的输出,使电机快速起动至给定转速。仿真分析与实验结果均证明了系统控制策略的可行性与有效性。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.
