This paper proposes a new semiconducting-type fault current limiter(FCL) using the digital signal processor(DSP) to improve the instantaneous voltage drop and to reduce the falut cureent of power system. The proposed FCL used a insulated gate bipolar transistor (IGBT) as a commutation element. Next, the DSP is used in proposed FCL in order to detect the fault current at high speed. The examination was carried out using equipment of small capacity in order to demonstrate the effectiveness of the proposal technique.
