Abstract

A solid-state circuit breaker comprises a breaker housing and an air gap driving mechanism that is a permanent magnet based. The air gap driving mechanism includes a pair of opposing contacts, a first permanent magnet to generate a static magnetic field and a coil actuator to generate a dynamic magnetic field. The first permanent magnet and the coil actuator are positioned relative to each other such that the dynamic magnetic field generated by the coil actuator can either enhance or cancel the static magnetic field of the first permanent magnet. Hence a combination of the static magnetic field from the first permanent magnet and the dynamic magnetic field from the coil actuator can either drive the pair of opposing contacts open or drive the pair of opposing contacts close.
