查询词典 ignition rectifier

Since the harmonic spectrum of ac-side phase voltage of PWM rectifier is influenced not only by pulse modulation style, but also by the parameters of close-loop adjustors, a three-phase voltage source inverter controlled by TMS320F2812 has been built to obtain the harmonics purely generated by SVPWM and verify the algorithm. Power analyzer PZ4000 has been adopted to acquire experimental results.

由于PWM整流器交流侧相电压的谐波频谱不仅与脉冲调制方式有关，还受到闭环调节器参数的影响，因此该文搭建了以TMS320F2812为控制核心的三相电压型逆变器系统以得到单纯由SVPWM产生的谐波频谱，并对该算法进行验证。
