Abstract

This paper presents the problems regarding to the behaviour of current distribution among paralleled thyristors. They are addressed with the experiment of high current transformer-rectifiers. The system is further implemented in the Power System Blockset, now SimPowerSystem, in MAT-LAB/Simulink. The Fourier-series-based model is employed to study both the system performance and the device internal behaviour. The experiment and simulation reported in this paper offer valuable insight into the parallel operation of thyristors
