Abstract
Within a switching network of the type wherein at least one GTO device is rendered conductive or non-conductive to control the flow of current through a load, current is drawn from the gate of the GTO device and a shunt path is connected across the main conduction path of the GTO device simultaneously in response to a turn-off signal.
Claims3
In a switching network of the type wherein at least one GTO device is rendered conductive or non-conductive to control the flow of current through a load, the improvement comprising:
- first and second transistors, said first transistor having its main conduction path connected to conduct current away from the gate of the GTO device, said second transistor having its main conduction path connected in parallel with the main conduction path of the GTO device, said first and second transistors having their control electrodes commonly connected to receive the turn-off signal.
