The switching voltage generated by the transformer 3 for 3 hours is supplied to a rectifying load 9 through a diode 7 and a capacitor 8.

化を抑える閉ループ回路となっている。The above voltage fluctuation is amplified by the error detection circuit 10 and the drive circuit 11 to control the base current of the switching element 20. This turns on the switching of switch element 2.
/ OFF duty is a closed loop circuit that suppresses changes in the voltage applied to the load.

が増加する。又、逆に入力電源の高い電圧でス。That is, in order to extend the control range to a low input power supply voltage, it is necessary to sufficiently drive the switching element 2 by the feedback winding 3C. However, as the input power increases, the voltage generated in the feedback winding increases, and an excessive Pesumi current is supplied to the switch element 2, resulting in poor rise and fall times when the switch element 2 turns on and off. and losses will increase. Also, conversely, a high input power supply voltage will cause a problem.

ス３の帰還巻線を設計すると、入力電源が低い時に負荷
電圧が一定にならないという欠点があった。If the feedback winding of the transformer 3 is designed to supply an appropriate pace current to the switch element 2, there is a drawback that the load voltage is not constant when the input power source is low.
本発明は上記欠点を除去し、広範囲な入力電源の変化に

Parts that are equivalent to those in the figure are given the same reference numerals as in FIG. 1. The difference is that a Zener diode 12 and a transistor 13 are arranged in series from the feedback winding sC of the transformer 3, and that the feedback resistor 5 is divided.

。That is, when the input power supply 1 becomes high, the voltage applied to the feedback winding 5C of the transformer 3 becomes high, and this exceeds the threshold of the Zener diode 12. As a result, the transistor 13 is turned on, and the current supplied to the pace of the transistor 2 is bypassed by the resistor 14. This can prevent an excessive pace current from flowing into the pace of transistor 2. When the input power becomes low, Zener diode 12 is cut off, and transistor 13 is also cut off.
Since the pace current is not bypassed by the resistor 14, the transistor 2 can be sufficiently turned on and off, making it controllable.
