Abstract

This paper discusses the design of discrete switching sequences for synthesizing sinewaves in power-electronic circuits and drives. The discrete-level sinewave approximations described in this paper can be implemented with reduced switching losses, in comparison to typical pulse-width modulation patterns, and with user-selectable harmonic content. We present two design algorithms, including an algorithm based on simulated annealing. The algorithms allow the engineer to select switching sequences that meet desired objectives or characteristics in almost any context. In addition, we demonstrate the use of these sequences experimentally in a practical application
