Abstract
A power supply output device converts an input from a DC-DC converter into a bipolar voltage output of a gate driver circuit driving a power switch. The power output supply device includes an adjusting circuit to measure an output of the gate driver circuit at the gate of the power switch, and to adjust the bipolar voltage output in order to maintain the output of the gate driver circuit at a predetermined voltage. The power supply output device provides a cost-effective technique to regulate the peak positive voltage input into the gate of the power switch at a required voltage, regardless of any fluctuations or losses.
