<p>PURPOSE:To obtain an efficient power source by integrally constructing the first low voltage transformer and the second high voltage transformer, thereby enabling to omit the primary side drive circuit of a high voltage inverter transformer. CONSTITUTION:One end of the secondary winding W1 of an inverter transformer 4 is grounded, and the other end is connected to one end of 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 transistor TR1 is connected to the primary winding. On the other hand, a rectifier 9 which has a diode D2, is connected to the secondary winding of the transformer 8. The rectifier 9 is provided in a transformer integral with the transformers 4, 8.</p> |
