POWER SOURCE DEVICE
Document Type and Number:
Japanese Patent JPS6084968
Kind Code:
A
Abstract:
PURPOSE:To enable to omit the primary side drive circuit of a high voltage inverter transformer by integrally constructing the first low voltage transformer and the second high voltage transformer, and connecting the first and second transistors via a semiconductor switching element. CONSTITUTION:One end of the secondary winding W1 of an inverter transformer 4 is connected to the primary winding of an inverter transformer 8. A series connection of a resistor R3 and a capacitor C1 is coupled in parallel with the primary winding of the transformer 8, and the collector of an emitter-grounded transistor TR1 is connected to the primary winding. On the other hand, a rectifier 9 which has a diode D2, a capacitor C2 and resistors R4, R5 is connected to the secondary winding of the transformer 8. The rectifier 9 is provided in a transformer integral with the transformers 4, 8. Thus, the primary side drive circuit of the high voltage inverter transformer can be eliminated.
