摘　　要：根据自然采样SPWM基本原理,结合SABER软件仿真分析了调制系数、载波频率、互锁时间对逆变器输出电压的影响。逆变器系统的仿真结果和试验结果的对比验证了SABER软件仿真结果的准确性,同时也说明LC滤波器对高频谐波良好的抑制能力。According to the basic principle of natural sampling SPWM, the software of SABER is used to simulate and analyse the factors that influence inverter output voltage. The factors include modulation coefficent, carrier wave frequency and dead time. By contrast the simulation and experimental resuits of inverter system, it can be verified the accuracy of simulation, and it shows that LC filter can filter the high frequency harmonic effictively.
