Abstract
A power supply output device converts an input from a DC-DC converter into a bipolar voltage output that is supplied to a gate driver circuit driving a power switch. The power output supply device includes a clamping circuit that sets the voltage values of the bipolar voltage output at a predetermined voltage through switching of one or more switching elements. The power supply output device allows shunting of a high current on the negative side so that the required bipolar voltage output is reached very rapidly.
