Abstract :
Optimal Pulse Patterns (OPPs) permit setting the switching frequency of power converters to a low value without compromising on Total Harmonic Distortion (THD). This paper presents the algorithm of calculating OPPs for Medium Voltage converters. The calculation procedure is explained in detail. Results are discussed and an efficient method is proposed to speed up and simplify calculations.
