Abstract

This paper proposes a novel method of suppressing the inrush current of transformers. A small-rated voltage source PWM converter is connected in series to the transformers through a matching transformer. As the connected PWM converter performs a resistor for the source current, no inrush phenomena occurs. The basic principle of the proposed method is discussed. The validity and excellent practicability of the proposed method is confirmed by digital computer simulation using the PSCAD/EMTDC. Simulation results demonstrate that the proposed method can perfectly supprress the inrush phenomena.
