Due to the distributed energy resources (DER) and renewable energy integration, there is a growing need for reliable, fast and safe circuit breaking technology. Solid state circuit breaker (SSCB) uses solid state devices as a tripping unit and provides faster tripping with no arcing. The main challenge of an SSCB is to design a simple and cost-effective voltage clamping circuit. This paper proposes a design method of RC and metal-oxide varistor (MOV) based voltage clamping circuit for SSCB. An equivalent circuit is derived from which the suitable values of R and C are determined. Moreover, the advantage of using MOV is also explained. The proposed design is verified in a harware prototype of 240V, 6A SSCB.
