Abstract

PURPOSE: To obtain plural numbers of DC voltage through a simple circuit constitution, by adding the voltage multiplying rectifier to the switching stabilized power supply circuit using an autotransformer.
CONSTITUTION: With make of the power source, the positive feedback oscillating circuit starts oscillations. And the autotransformer 20 is driven by the output of the transistor TR4 to generate the AC signal having the prescribed amplitude VO at the collector of the TR4. The AC signal is rectified through the rectifying circuit 13 to obtain the DC voltage of the value VO-2VF (Vf: forward drop voltage of diode) at the terminal 14. At the same time, the AC signal generated at the collector of the TR4 is rectified through the voltage multiplying rectifier 21 to obtain the DC voltage of the value -VO+2Vf at the terminal 16. Then the DC voltage obtained at the terminal 14 is detected by the Zener diode 17, and the oscillating circuit is controlled via the TR18. As a result, the stabilized plural numbers of DC voltage having the same absolute value can be obtained through the terminals 14 and 16.
