Abstract
This paper deals with an improved current source using full-bridge converter type for thyristor valve test of HVDC system. The conventional high-current and low-voltage source of synthetic test circuit requires additional auxiliary power supply to provide the reverse voltage for the auxiliary thyristor valve during turn-off process. The proposed circuit diagram to provide the reverse voltage is extremely simple because no additional component is required. The reverse voltage can be obtained from the input DC voltage of the high-current and low-voltage power supply. The operation principle and design method of the proposed system are described. Simulation and experimental results in scaled down STC of 200 V, 30 A demonstrate the validity of the proposed scheme.
