The isolated direct gate driver with Drive-by-Microwave technologies can directly drive a power switching device by wireless power transmission of RF modulated signal through the electromagnetic resonant coupler and requires no additional isolated voltage source. In order to improve the performance such as a fall time characteristic and a power consumption of the gate driver, a new direct gate driver...
The wireless power transmission technology using an electro-magnetic resonant coupler (EMRC) has been applied to an isolated direct gate driver for GaN power switching devices. This direct gate driver with the Drive-by-Microwave technologies dose not needs an additional isolated voltage source and a photo-coupler because it can supply an isolated gate signal and signal power all together. The wireless...
