Abstract
PURPOSE:To lessen the influence of the fluctuation of supply voltage on output voltage by employing the voltage fluctuating in the same direction with that of the voltage fluctuation of the power source as supply voltage to a timing circuit for setting the width of the time of impression of the supply voltage. CONSTITUTION:A transistor 5 for interrupting current is connected to the primary winding 2 of a transformer 1, while an output is supplied from the secondary winding 3 to a load Rl. In addition, the transformer 1 is provided with the 3rd winding 4, which is connected with a synchronizing pulse generating circuit 11, and by the output thereof a flip-flop 8 is controlled and thereby the transistor 5 and a transistor 6 which is connected to the timing circuits R1 and C1 to which the same voltage is given with the supply voltage are controlled, while the output voltage is detected by a detecting circuit 10 and given to a comparator 7, whereby the flip-flop 8 is controlled. Therefore, dependence of the fluctuation of the output voltage on that of the supply voltage can be reduced and thus stable control characteristics can be obtained.
