Abstract
A solid-state circuit breaker comprises a solid-state device configured between line-in and line-out terminals, an air-gap forming apparatus coupled in series with the solid-state device to complete a current conducting path and a sensing and control unit to control a gate of the solid-state device. It further comprises a first switching component coupled in series with an actuator coil across a connection point after an air gap and a neutral such that the sensing and control unit to control a gate of the first switching component. It further comprises a second switching component coupled between the line-out terminal and a terminal between the actuator coil and the first switching component such that the sensing and control unit to control a gate of the second switching component. The actuator coil is configured to discharge and dissipate a recovery voltage associated therewith an inductive load.
