摘　　要：针对开关电感型Quasi-Z源逆变器,采用Matlab/Simulink仿真平台对空间矢量脉宽调制(SVPWM)策略进行了仿真研究。仿真结果表明,与简单升压调制策略相比,SVPWM调制策略具有开关频率低、直流母线电压小、调制度较大等优点,可以提高直流母线电压的利用率。For switched-inductor Quasi-Z-source inverter, simulation study on SVPWM modulation strategy was carried on through Matlab/Simulink simulation platform. Simulation results show that compared with simple boost modulation strategy, the SVPWM modulation strategy has the advantages of low switching frequency, small DC bus voltage and large modulation level, improving the utilization of DC bus voltage.
