Abstract
A gate driver includes: an input pin for receiving switching control information from a controller; an output pin for driving a control terminal of a power transistor; a power supply pin for receiving power from an external supply; an input side electrically connected to the input pin; an output side electrically connected to the output pin and the power supply pin; and an isolation structure galvanically isolating the input side and the output side from one another. The output side is configured to transfer a fraction of the power received at the power supply pin to the input side over the isolation structure for powering the input side. The input side is configured to convey the switching control information received at the input pin to the output side over the isolation structure. A power electronic system that includes the gate driver is also described.
