Abstract - The Voltage source converter (VSC) based HVDC system is a relatively new technology for low and medium power transmission which can be connected to weak or even passive AC networks and is capable of supplying or absorbing reactive power according to the system operating conditions. The main switching component of the VSC is a high power high frequency static switch. A new voltage source inductive filtering converter (VSIFC) for HVDC Light transmission system which is mainly composed of the inductive filtering (IF) transformer and the related full-tuned (FT) branches with the commutating function for the self commutated converter. This paper concerns on the technical feasibility on the application of VSIFC in HVDC-Light systems. A typical test system for the proposed VSIFC-based HVDC-Light transmission is established in MATLAB/SIMULINK. Harmonic filters are installed on the PCC. The coupling transformer not only provides the suitable line-voltage for self-commutated converter, but also utilizes its leakage reactance efficiently to exchange active and reactive power between VSC and power system. It is worth to remark that although there is a special commutating reactor for VSC station, with the consideration that provide the suitable line-voltage for the operation of VSC station and prevent the 3-time harmonic currents from flowing into PCC, the coupling transformer is necessary to be installed.
