In this paper, a flux-lock type superconducting fault current limiter (SFCL) integrated with a voltage-controlled voltage source inverter (VC- VSI) is proposed. The suggested equipment, which consists of a flux-lock type SFCL and a VCYSI, can perform the fault current limiting operation from the occurrence of a short-circuit, In addition, it can compensate the reactive power that the nonlinear load requires and also perform the un interruptible power supply (UPS) as well as the load voltage stabilization by controlling the amplitude and the phase of the inverter's output voltage. The specification for a test model was determined and its various functions such as the fault current limiting and the power conditioning operations were presented and analyzed via computer simulation. Through the analytical results based on the computer simulation, the validity of the analysis was confirmed and its multi-operation was discussed.
