A gate driver, the gate driver comprising:
- an RF source;
- a PWM controller;
- an edge detector and pulse generating circuit operably connected to the RF source and PWM controller;
- and
- a rectifier circuit and a signal recovery circuit,
- wherein the edge detector and pulse generating circuit are connected to a primary side of a transformer, and the rectifier circuit and the signal recovery circuit are connected to a secondary side of the transformer.
A method for driving a drive circuit, the method comprising:
- modulating an RF signal with a PWM signal to create a primary signal, wherein the primary signal is applied to a primary side of a transformer;
- and
- producing a power signal and a recovered PWM signal from a secondary signal from a secondary side of the transformer,
- wherein the recovered PWM signal and the power signal drive the drive circuit.
