摘要
介绍了一种LC型正弦波滤波器的设计方法,并将该滤波器应用于交流励磁双馈电机转子侧变换器的输出端,减小了PWM电压长线传输带来的负面效应,防止了转子侧开关谐波通过定转子气隙磁场耦合到定子侧,定子电压的波形质量得到了改善。
A design method of LC type sine-wave filter is proposed in this paper. rotor side converter output of AC excited double-fed machine. Long cable negative waveform voltage is reduced and switching harmonic at rotor side is avoided to affect so stator side voltage waveform is improved. The filter is used at the effectiveness for PWM the stator side voltage.
