| 摘 要： | 根据开关函数法和调制理论,推导得出了充电机的谐波模型。该模型将充电机的时域非线性特征变换成频域线性矩阵,它不依赖于充电机端口的运行情况。当充电机的参数及基波初始相角确定后,该模型矩阵为常矩阵。同时,根据谐波叠加特性,得到了多台充电机的谐波模型。通过与时域仿真的结果对比,验证了该模型的正确性。

| Abstract: | According to the switching function method and modulation theory, the EV charger＇s harmonic model is derived. This model transforms the nonlinear characteristics in timedomain into a frequency domain linear matrix, independent of the operation status of the EV charger＇s port. With the parameters of EV chargers and the initial phase given, the model is a constant matrix In addition, this paper also derives the model of several EV chargers working together by harmonic superposition characteristics. Compared with time-domain results, this model proves to be accurate. |
