Abstract: PURPOSE: To obtain a current-mode switching stabilized power-supply apparatus which improves the power factor by a method wherein the side of the DC output of a switching stabilized power supply is insulated from the side of an AC input by a transformer, a capacitor on the primary side of the transformer to smooth the full-wave-rectified voltage of an AC input voltage is omitted or made to have very small capacitance and the inrush current of an AC input current is eliminated. CONSTITUTION: An oscillator OSC sets a PWM latch FF at every switching cycle, and it turn on an FET Q1. On the other hand, a feedback voltage Vfb as the voltage deviation output of a DC output Eout is taken out via voltage divider resistors R2, R3, a shunt regulator 2, a photocoupler PC1 and filters Rf, Cf. A comparator CP1 resets the latch FF when the voltage VR1 of a transformer-primary-current detection resistor R1 exceeds the feedback voltage Vfb, and it turns off the FET Q1. When the Q1 is PWM-controlled, an AC input current Io becomes trapezoidal waves having a peak value corresponding to the voltage deviation of the DC output.
