Abstract
An apparatus is arranged to break an electrical current. The apparatus includes: a mechanical switch leg including a first winding of a mutual inductor and a mechanical switch connected in series; a semiconductor switch leg including a second winding of the mutual inductor and a semiconductor switch connected in series; and an overvoltage protection circuit. The mechanical switch leg and the semiconductor switch leg are connected in parallel and a self inductance of the second winding is lower than a self inductance of the first winding. A corresponding DC circuit breaker and AC current limiter are also presented.
