一种用于多千瓦级和数十兆赫兹开关功率放大器的基于有源钳位源的SiC谐振栅极驱动技术

Resonant gate driver (RGD) is an effective method to achieve gate driving loss reduction and noise suppression at high frequency. Most RGDs require at least two switches to constitute the bridge structure, which suffers from the difficulty of accurate dead time control at tens of MHz. The single-switch RGDs are easy to implement but can only generate fixed duty cycle driving voltage and operate at...
