The grid is becoming increasingly flexible and controllable with the extensive application of the power electronic equipment including the series voltage source inverter(SVSI). However

it is important to protect these devices under the short-circuit fault. This paper reviews researches on series voltage source inverters with fault current-limiting(SVSI-FCL)function. Based on the safety analysis of these devices

the review introduces the concept of SVSI-FCLF. It suggests classifying SVSI-FCL into two groups: the control scheme optimization group and the existing topology improvement group. Then

an emerging technology is introduced in detail. Finally

the key issues and the application prospect of the SVSI-FCL are addressed. The review aims to draw attention to SVSI-FCL research and call for new ideas to be contributed to extend and enrich the available pool of SVSI-FCL concepts.
