摘要
多电平谐波消除需要求解非线性方程组,采用牛顿迭代法存在初值难以选择的问题。通过对时域信号进行沃尔什变换,再将沃尔什域转换到傅立叶域,就可以得到开关角与谐波幅值的线性方程组,该线性方程组具有很好的实用价值。仿真和实验结果证实了该方法的分析的正确性。
It is necessary to solve the nonlinear equations for elimination the harmonics,but there are some difficulties to select the initial value.Changing the time domain signal to Walsh domain,then converting to Fourier series, the linear equations about switch angle,DC source voltage and harmonic amplitude can be built,which are useful in practice. Experiment verified the correctness of this method.
