Abstract
PURPOSE:To manufacture power supply devices with small size and low cost, reduced dispersion and stable operation, by picking up a control signal controlling an output of a transformer from a connecting point between a smoothing capacitor and a control resistor of a series circuit. CONSTITUTION:A charge/discharge current of capacitors 20 and 24 is changed when a load connected to an output terminal 19 or a power supply voltage changes, and a voltage generated in resistors 21 and 22, that is, a control voltage outputted at a control terminal 28, is changed and this changed control voltage is fed back to an inverter 12. Then, the inverter 12 controls the output voltage of a transformer 13 for the inverter to the direction that the change in the control voltage can be reduced. Thus, an output current from an output terminal 19 is always kept constant.
