Abstract

See full text

Unique systems, methods, techniques and apparatuses of solid state circuit breaker protection are disclosed. One exemplary embodiment is a solid state circuit breaker comprising a primary switching device including a first terminal and a second terminal and a voltage clamping circuit coupled in parallel with the primary switching device. The voltage clamping circuit includes a metal-oxide varistor (MOV) coupled in series between the first terminal and an auxiliary semiconductor device, the auxiliary semiconductor device being arranged so as to selectively couple the MOV with the second terminal, and a bypass circuit coupled between the first terminal and the auxiliary semiconductor device.
