Abstract :
GTO applications limitations are investigated under hard and soft switching topologies as device output power and device switching frequency are simultaneously increased. Characterization test results and a P-Spice GTO model simulating device turn-off are used in the investigation. The most significant improvement under soft switching is seen to be an elimination of the voltage spike normally associated with hard switch GTO turn-off. The impact of this on turn-off capability and switching frequency is investigated in detail
