Abstract :
A technique is described to model phase-shifting power converter transformers in the harmonic domain. The model has been incorporated into a unified Newton solution technique which permits solution of high-pulse installations with parallel DC connections. A variety of test cases are included to illustrate the characteristics of a 24-pulse installation under both ideal and nonideal conditions. The results show that the characteristic DC harmonics for an individual power converter in a multi-pulse parallel connection installation increase with pulse number rather than decrease as with a series connection
