| 摘 要： | 分析了可用于大功率牵引传动领域的空间电压矢量同步脉宽调制的实现原理,给出了牵引逆变器输出电压波形满足同步、三相对称、半波对称的条件.同时得到了在开环变频调速过程中,采用同步SVPWM控制时,逆变器输出电压电流仿真波形,并对其进行了谐波特性分析.仿真结果证明了采用同步空间矢量脉冲宽度调制的一系列优点.

| Abstract: | The principle of space-vector-based generation of synchronized three-phase PWM waveforms with three-phase,half-wave symmetries was analyzed.Simulation model was built to realize this strategy with different pulse numbers in open loop VVVF.Voltage and current waveforms corresponding to different pulse number were presented,harmonic spectral analysis was also given.Simulation results prove the good performance of synchronized SVPWM. |
