摘　　要：基于调制理论建立了交直交变频器的开关函数模型,针对采用不可控整流和逆变器PWM控制的交直交变频器模型提出了电网输入端的谐波和间谐波参数计算方法。针对典型算例对电网输入端主要次谐波和间谐波的幅值和频率参数进行了计算,并通过时域仿真验证了计算方法的有效性。In this paper,the switching function model of the AC/DC/AC frequency converter is established based on the modulation function theory,and the calculation method of harmonic and interharmonic parameters at the input terminal of power grid is proposed for AC/DC/AC frequency with using uncontrolled rectifier and pulse width modulation(PWM)control inverter.The amplitude and frequency parameters of main subharmonics and interharmonics at the input terminal of power grid are calculated for a typical example,and the effectiveness of the method is verified with time domain simulation.
