摘要： An isolated gate driver includes a transformer including primary and secondary windings, a synchronous rectifier connected between the secondary winding and an output terminal of the isolated gate driver, a first switch including a first terminal connected to a supply voltage, a second switch including a first terminal connected to the supply voltage, a first damping resistance connected between a first terminal of the secondary winding and a second terminal of the first switch, a second damping resistance connected between a second terminal of the secondary winding and a second terminal of the second switch, a first inverter including an input connected to the first terminal of the secondary winding and an output connected to a gate terminal of the first switch, and a second inverter including an input connected to the second terminal of the secondary winding and an output connected to a gate terminal of the second switch.
