摘　　要：此处提出了一种内嵌式Boost电路的超稀疏矩阵变换器(USMC)拓扑结构,用于解决USMC电压传输比较低的问题。这种内嵌式Boost电路的工作原理在于在USMC的直流环节增加Boost电路,结合空间矢量脉宽调制(SVPWM)策略,推导出新型USMC拓扑结构的电压传输比及输出功率因数范围。相比于普通USMC拓扑结构,能够提高直流环节的输出电压,使逆变级输出更高的线电压,从而拓宽输出电压传输比范围,而且能降低输出电流的谐波畸变率。最后通过仿真和实验结果验证了该理论的正确性和可行性。An ultra-spare matrix converter(USMC) topology with embedded Boost circuit is proposed to solve the problem of low voltage transmission ratio in USMC.The embedded Boost circuit works by adding Boost circuits in the DC link of the USMC,and combining with the space vector pulse width modulation(SVPWM) strategy,the voltage transmission ratio and output power factor range of the new USMC topology are deduced.Compared with the common USMC topology,the output voltage of the DC link can be improved.The inverter can output higher line voltage,so as to broaden the range of output voltage transmission ratio,and can reduce the harmonic distortion rate of output current.Finally,the correctness and feasibility of the theory are verified by simulation and experimental results.
