Abstract

A current interrupter (1) for a circuit-breaker comprising a contact arrangement (10) adapted to interrupt current (i) and comprising a first contact (12) and a second, movable contact (14); a mechanical drive train (20) mechanically connected to the movable contact (14); an actuator (30) mechanically connected to the mechanical drive train (20) and comprising an electro-magnetic forcegenerating device (30), a current driver (40) comprising an energy storage (42) connected to the actuator (30) for energizing the electro-magnetic force-generating device (30) and a current reference generator (50) adapted to provide a current reference signal to the current driver (40). By providing a current controller in the current driver (40) comprising semiconductor devices having turn-off capability and being adapted to provide switched mode control of discharge current from the energy storage (42) in accordance with the received current reference signal from the reference generator (50), improved control of the opening and closing operation of the current interrupter is achieved.
