Abstract

PURPOSE:To realize the size reduction for the device as a whole as well as a high- efficiency control for the large-power switching transistor by installing the thyristors as both the current supply route and the short-circuit route of the current supply source and then giving an individual control to each thyristor. CONSTITUTION:For switching transistor Tr11, the collector is connected to power source VCC via load resistance R0 along with the emitter earthed to be drivan by driving circuit 10. For circuit 10, thyristor 16 is provided to the current supply route along with thyristor 18 provided at the short-circuit route of power supply source respectively. And the ignition is controlled by control circuit 21 for the both thyristors. With the individual control given to thyristors via circuit 21, the size can be reduced for the device as a whole. And as a result, a highly efficient control is ensured for large-power switching Tr11.
