Abstract

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
