Asymmetrical Decoupling Model of Six-Phase Autotransformer and its Application

Article Preview

Abstract:

In order to analyze the effect of asymmetry of phase-shift transformer on 12-pulse ac-dc converter, this paper sets up a decoupling model of delta-connected autotransformer. Via analyzing coupling circuit of autotransformer, the relation among branch voltage, branch current, node voltage and node current is built, and base on the relation, an admittance matrix containing the information about the connection way and electrical quantities is concluded. Utilizing the matrix, the proposed model is established. Simulation and experimental results show the validity of the model when simulating the asymmetry of delta-connected transformer
