A parallel evolutionary algorithm for optimal pulse-width modulation technique in power systems
Pages 725 - 730
Abstract
Pulse-Width Modulation (PWM) based on the elimination of low-order harmonics needs to deal with a class of systems of nonlinear equations whose right-hand terms are changed with time, moreover, these systems of nonlinear equations often have multiple solutions which are difficult to handle with conventional techniques. In this paper, an effective asynchronous parallel evolutionary algorithm is proposed to solve these systems of nonlinear equations so that we can obtain the switching angles for eliminating the low-order harmonics, accordingly, pulse patterns are optimized. In the paper, we give the detailed description of parallel algorithm, and the numerical results show that we can obtain the switching angles for a set of amplitudes and phase angles of the low-order harmonics
