Abstract :
A 6.5 kV controllable freewheeling diode (CFD) has been realized for the first time. A forward voltage VF up to 2.5 V (66 A/cm2) and a VF rising over 1.8 V between gate off state and gate on state at 125degC temperature was realized. A reduction of the recovery charge Qrr and consequently reverse recovery energy Erec of more than 35% have been achieved in comparison with a state of the art 6.5 kV emitter controlled diode.
