Direct commutation device for use between e.g. diodes, in circuit-breaker arrangement, has driver circuits connected with programming and control unit via signal lines and with circuit-breaker arrangement via control signal lines

摘要

The device has an auxiliary signal circuit (2-3) connected with a programming and control unit (1) via a signal line (18-1). Two control part circuits (2-4, 2-5) are connected with the circuit (2-3) via auxiliary signal lines (15-1, 15-2). Two driver circuits (2-6, 2-7) are connected with the control part circuits by driver control lines (16-x) and with the programming and control unit via the signal lines (20-1 to 20-4) for presetting driver part current levels on a programming interface (20) and with a circuit-breaker arrangement (3) via control signal lines (7-1, 7-2). An independent claim is also included for a method for direct commutation between power-electronic control units in a circuit-breaker arrangement.
