| 摘 要： | 本文通过MATLAB仿真和博立叶分析，分析了PWM逆变电路的有功功率和能量交换过程，推导出能量交换的计算公式，通过对实际例题的计算，验证了逆变电路交直流两侧的能量守恒关系。逆变电路交流侧的能量交换，使得直流侧的电流出现了波动，由于能量交换的频率是基波频率的两倍，所以在逆变电路的直流侧就出现了2次谐波电流。搞清楚这些过程和关系将有利于更好地理解交流电路的无功功率。

| Abstract: | By means of Matlab software and the Fourier analysis method,the active power and the exchange energy of the PWM contravariant circuit are analysed,and the calculation formula of the exchange energy in the circuit is deduced.Through calculating the examples,the energy conservation relation of the contravariant circuit is proved.The energy exchange of AC side of the contravariant circuit makes DC side appear current fluctuation.Because the frequence of the energy exchange is twice of the fundamental frequency... |
