HIGH POWER TRANSISTOR DRIVING CIRCUIT

摘要

The circuit providing the stability, reliability and downsizing by using MOSFET comprises: a section (1) supplying the stabilized power; a rectification circuit (2) for supplying the full-wave rectified alternating current of power supply section (1) to the driving circuit (4); a section (3), which drives the circuit (4) through the transistors (Q3,Q4) receiving the control signal from the control circuit using the optical fiber; a configuration circuit outputting the ON side current and the OFF side current to the base of passive driving high power transistor.
