PURPOSE:To stabilize the current of the entire power source by controlling the current flow rate of the primary side of a transformer to stabilize the rectified output of one output windings as constant voltage or current and connecting a constant current circuit between the rectified output terminal of the other output winding and a load. CONSTITUTION:An input voltage is switched by a switching circuit 2, and supplied to the primary winding of an inverter transformer 3. The secondary side output of the transformer 3 is rectified by a rectifying diode 4, a condenser 5 and a resistor 6. A corona current flowed to a charger is detected by a current detector 8, and the detected output is negatively fed back to a series regulator 1 through an error amplifier 10. A constant-current circuit having a high withstand voltage transistor 11, a bias voltage 12 and a resistor 13 is provided at the rectified output terminal of the other secondary winding. |
