摘要
针对高性能蓄电池测试系统主变流电路采用的SVPWM和SPWM调制方法,分析了二者间的内在联系,并进行了性能比较。在数字化控制系统中,较SPWM方案,SVPWM方案不仅提高了逆变器的直流电流利用率,且减小了输出电流的纹波系数,降低了谐波污染,使电路更接近单位功率因数运行。
This paper compares and analyzes SPWM and SVPWM for the converter of high performance power accumulator battery test system. Compared with SPWM in digital control system, SVPWM not only improves the inverter DC current utilization, reduces output current ripple factor, but also decreases harmonic pollution, makes the circuit power factor more closer to unity.
