Abstract In this paper, a novel voltage source converter is proposed. It is composed of a 12- pulse converter and an auxiliary circuit. The auxiliary circuit injects DC voltage via the mid point of the 12-pulse converter. Proper injection ratio and frequency parameters are selected to convert the standard 12-pulse into 60-pulse configuration without using PWM or increasing the number of bridges, thus the voltage and current can fulfill the THD limit without conventional filter. As the main bridges operate at fundamental frequency, the switching lose is relatively low. This converter may be widely used in the HVDC and FACTS system. The principle and control strategy of the proposed converter are described. Its operational feasibility is also verified by digital simulation using the PSCAD/EMTDC package.

Key words： Multi-pulse converter voltage source converter auxiliary circuit voltage injection
