The continuous enlargement of fault current has great influence on the stability and safety of power system. Super conductive Fault Current Limiter （SFCL） is a current limiting device which combines the superconducting technology with the electric technology, which is a effective way to solve the problem. And DC biased iron core type SFCL has the better application prospect. According to the investigation and extensive collection of fundamental data, the operating principle of this type SFCL was introduced in this paper. Through analyzing the research and development situation at home and abroad, its advantages and disadvantages were compared. The key technologies in design procedure and main problems constrainting its industrial application were summarized. Finally, technical proposal of the DC biased iron core type SFCL was proposed, and the application prospect of it was predicted.
