Abstract
A drive circuit that provides isolated power for gate drivers of IGBT and DMOS transistors used in inverters. The drive circuit provides power to an isolated gate driver that receives a control voltage, and in response to the control voltage, uses the power from the drive circuit to output a gate control signal that is coupled to an isolated gate bipolar transistor. The drive circuit includes a start-up circuit coupled to a supply voltage, a resonant circuit coupled to the start-up circuit and the supply voltage, and a rectifier circuit coupled to the start-up circuit and the resonant circuit, and having logic to output a power signal that is coupled to the isolated gate driver, the rectifier circuit is also coupled to the isolated gate driver at a common node.
