Abstract
Disclosed is a circuit breaker apparatus, including a first switching assembly, a first controller, a second switching assembly and a second controller. The first switching assembly is connected in series between a positive pole of a power supply and a load. The first switching assembly includes multiple first switching units in series. The first controller is electrically connected to a first pre-set reference potential of the first switching assembly. The first controller is electromagnetically coupled with each first switching unit through a first transformer unit. The second switching assembly is connected in series between a negative pole of the power supply and the load. The second switching assembly includes multiple second switching units in series. The second controller is electrically connected to a second pre-set reference potential of the second switching assembly. The second controller is electromagnetically coupled with each second switching unit through a second transformer unit.
