ABSTRACT:
Power supply switching apparatus comprising an output switch for supplying power from a power supply to a load connected to an output terminal, a driver for controlling turn-on of said output switch, and a control signal generator for controlling said driver to produce a desired progressive turn-on characteristic. The apparatus also includes overload detection means responsive to a parameter of the load relative to a reference signal to provide a fault signal in case of detection of an overload condition after a turn-on phase of said output switch. The control signal generator is responsive to the reference signal to activate said overload detection means to provide a fault signal during the turn-on phase of the output switch even in presence of a severe overload condition at the output terminal.
