In this paper, the authors propose a novel application for a three-phase, solid-state, fault current limiter (FCL), consisting of a three-phase full-bridge rectifier and a DC reactor (DCR). Its configuration, operating principle, and a simple design method of the DCR, are presented. The proposed method is a combination of the FCL and a synchronous generator, and the FCL is connected to the neutral-point of the synchronous generator. As a result, an indispensable transformer in the conventional FCL can be removed, and a feature that maintains the current-limiting effect at a one-line ground fault is also obtained. To construct a guideline for creating the optimum DCR design, the current-limiting performance of the proposed method is theoretically analyzed, and the relationship between the fault current to be limited and the required DCR-inductance is derived. The experimental results obtained on a laboratory model demonstrate the effectiveness of the proposed method and validate the theoretical analysis.
