Title:
CONTROLLER FOR CONTROLLING A GaN-BASED DEVICE AND METHOD FOR IMPLEMENTING THE SAME
Document Type and Number:
WIPO Patent Application WO/2022/217566
Kind Code:
A1
Abstract:
A controller for controlling a GaN-based semiconductor device. The controller is configured to receive a current sensing signal VCS which is indicative of a drain-to-source current of the GaN-based semiconductor device and generate a control driving signal VDRV to the GaN-based semiconductor device such that a gate-to-source voltage VGS applied to the GaN-based semiconductor device for switching on the GaN-based semiconductor device is stabilized to a voltage value equal to a reference voltage Vref over an on-time duration. Impact of the change in the voltage drop across the current sensing resistor to the operation of the GaN-based semiconductor device is eliminated.
