ABSTRACT:
The present application describes a system and method for driving a power supply device in an initial activation stage. In one embodiment, the method comprises providing in the power supply device at least one voltage regulator that is coupled with a voltage output adapted to supply a power voltage to a client device, receiving a signal indicative of an activation of the power supply device, and converting the at least one voltage regulator to an equivalent shunting circuit coupled between the voltage output and a reference voltage. Before power voltages are applied at the outputs of the power supply device, shunting paths are thus provided for releasing undesired currents.
