Title:
DC STABILIZED POWER SOURCE CIRCUIT
Document Type and Number:
Japanese Patent JPS605772
Kind Code:
A
Abstract:
PURPOSE:To output two DC stable voltages of opposite polarities by less number of parts by gathering a circuit which outputs a positive voltage and a circuit which outputs a negative voltage into one. CONSTITUTION:A coil 1 and a transistor 2 are connected in series with an input power source 40, and a diode 4 is connected from the collector of the transistor 2 to a positive voltage output terminal 9. Further, a capacitor 8 is connected between a positive voltage output terminal 9 and a GND. A capacitor 3 and a junction type silicon diode 6 are connected in series between the collector of the transistor 2 and a negative voltage output terminal 10, and a junction type silicon diode 5 is connected between the connecting point of the capacitor 3 and the diode 6 and the GND. Further, a capacitor 7 is connected between the terminal 10 and the GND.
