摘要

谐波消除脉宽调制(SHE PWM)策略的非线性代价函数(CF)难以求解。在求解CF之前，有一个好的初始猜测是非常重要的。本文探讨了一种在大型计算机上求解CF的新算法。提出了一种新的预测大自由度CF解的辅助算法。同时，建立了一种基于dsp的微处理器生成基本满意的切换模式的算法

Solving nonlinear cost function for optimal PWM strategy

It is difficult to solve the nonlinear cost function (CF) for selected harmonic elimination pulse width modulation (SHE PWM) strategy. It is extremely important to have a good initial guess before solving the CF. In this paper, a new algorithm for solving the CF on a mainframe computer is explored. A new auxiliary algorithm to predict the solution of the CF with a large degree of freedom is proposed. At the same time, an algorithm is established for DSP-based microprocessors to generate essentially satisfying switching patterns.<>
