Abstract

PURPOSE:To allow a power source circuit to rapidly respond to the variation in the current and to reduce the voltage fluctuation rate of the power source circuit by comparing the output voltage with a reference voltage and switching the output voltage in accordance with an oscillation signal. CONSTITUTION:When a voltage is applied to a transformer 1, an output signal A is simultaneously outputted from an oscillator 11, and a transistor 9 is controlled ON or OFF in accordance with a signal B having a duty factor varying by a multivibrator 10. When the transistor is interrupted, a switching circuit 4 will operate to form a negative feedback circuit 8, a comparator circuit 7 compares the output voltage with a reference voltage, the ON level of the switching circuit 4 is varied in accordance with the output signal from the switching circuit 4, is transformed by a transformer 3, is then rectified, and a desired DC voltage can be obtained. Since the responding speed of the power source circuit is thus fast, it can follow up the abrupt load variation.
