Wide bangap GaN power transistors can switch extremely quickly, e.g. current transitions in excess of 10 A/ns and voltage transitions in excess of 100 V/ns, but this presents a challenge in terms of keeping a system using such GaN transistors electromagnetically "quiet". With conventional gate driving techniques, to make transistors switch more "quietly", the transitions are slowed and losses increased (efficiency decreased). I am developing advanced gate driving techniques for wide bandgap GaN power transistors, aiming to eliminate any tradeoff between converter efficiency and electromagnetic compatibility.
