摘要
用Ｆｏｕｒｉｅｒ级数分析法分析了开关频率固定ＰＷＭ整流器的输入电流谐波。确立了系统参数的设计方法，提出了一种改进的电流控制方法。
In the paper the Fourier series method is employed to analyze the input current harmonic of PWM rectifiers with fixed switching frequency.Through the harmonic analysis,the rules to identify system parameters are obtained,and an improved method for controlling current is given.
