| Abstract(in English) | The turn-on transient of the cascode connected Polarization Super-Junction (PSJ) GaN-FET with 1200V class has been investigated. For standard cascode connection the gate of the high voltage device is connected to GND. However, for PSJ-FET experiments and device simulations both showed that faster turn-on is achieved when the gate voltage is clamped by the voltage source. The device simulations indicated that clamped gate voltage for PSJ-FET enhances the return of the holes to the on-state from the off-state which accelerates the turn-on transient. |
