GaN power transistors are becoming the gold standard for fast compact mains power switching – GaN HEMTs have no reverse recovery charge and can be designed with low on-resistance and low parasitic capacitance. However, their gates are fussy, and unbelievably fussy if all available speed is to be squeezed from this technology. Inappropriate gate drive ...
