As an example, in the case of a state-of-the-art power converter design based on GaN power switches, switching times are about 10 to 20 times faster than in conventional systems. Faster switching (5 ns typical) and a high voltage rail (≥600 V) result in increased voltage transients (≥120 kV/µs); therefore, common-mode transient immunity (CMTI) of isolated gate drivers plays key role.
