| 摘要: |
| 在整流级无零矢量调制的双级式矩阵变换器（TSMC）中，各个PWM周期内整流级输出平均直流电压为时变量，增加了逆变级的控制难度。将常规矩阵变换器双空间矢量调制技术推广到TSMC中，分析了整流级有零矢量的TSMC双空间矢量调制原理。由于整流级输出的直流平均电压在一个PWM周期内为恒值，逆变级的调制系数不需要在每个PWM周期内进行调整，简化了逆变级的控制。采用整流级与逆变级2级开关的协调控制仍能实现整流级零电流换流。用PSIM仿真软件对该调制策略进行实验，仿真结果验证了理论分析的正确性。 |

| Abstract: |
| The average DC output voltage of rectifier stage in a PWM cycle of TSMC（Two-Stage Matrix Converter) without zero vectors is variable， which increases the difficulty of inverter stage control. The two -space-vector modulation technology of conventional matrix converter is introduced to reduce the control difficulty of TSMC. The two-space-vector modulation principle of TSMC with zero vectors is analyzed. As the DC average output voltage of rectifier stage in a PWM cycle is constant，the modulation factor adjustment of inverter stage in a PWM cycle is avoided，which simplifies the control of inverter stage. Zero-current commutation is achieved with two-stage switching coordinative control. The modulation strategy is simulated with PSIM software and the correctness of theoretical analysis is verified. |
