Abstract
The present disclosure provides a controller for controlling a GaN-based semiconductor device. The controller is configured to receive a current sensing signal Vwhich is indicative of a drain-to-source current of the GaN-based semiconductor device and generate a control driving signal Vto the GaN-based semiconductor device such that a gate-to-source voltage Vapplied 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 Vover 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.
