て、パルス幅制御部１６にてパルス幅制御がなされる。A conventional switching regulator circuit of this type is configured as shown in FIG. 1, for example. However, the output of the Roy\7-circuit 10 is made into direct current by a rectifier circuit consisting of a diode [1.1)2 and a capacitor C1, and the output is switched by a chopper section having a switching transistor Q1.

とで周波数のずれが生じ、うなりを生じることになる。However, with this kind of circuit configuration, although the oscillation frequency of the - secondary side automatic oscillation circuit varies appreciably in response to input fluctuations and negative angle fluctuations, the secondary side has a constant frequency from the pulse generator. Since switching is performed using frequency pulses, a frequency shift occurs between the negative side and the secondary side, resulting in beats.
このことは、特に二次側をフルブ出力としで取出づ場合
、出力相互間で干渉が生じる欠点がある。This has the disadvantage that interference occurs between the outputs, especially when the secondary side is taken out as a full output.

三角波形とし、これでトランジスタＱ４を駆動づる。Now, the joint operation shown in this embodiment will be explained as follows. As mentioned above, since the self-excited oscillation circuit on the negative side is a Jensen circuit, the oscillation frequency hardly changes with respect to input voltage fluctuations or load voltage fluctuations. Therefore, since the secondary voltage waveform of the output transformer I-1 becomes a rectangular wave with a constant frequency, it can function as a pulse generator. In the present invention, this graph, 1i-shaped pulse 4 resistance R

However, its operation is explained in detail in d3.The triangular wave output is the base of transistor Q4 -[
Mitta electricity! During the period higher than 10, the transistor Q4 is conductive, turning on the switching 1 to transistor Q1, and conversely, during the period when the triangular wave output is lower than the voltage between the base and 1 mitter of the 1 transistor Q4, the transistor Q4 is non-conducting and the transistor Q1 is turned on. is spelled A). Furthermore, an output frost occurs due to the on/off operation of Ql. [Tsunardi A-Door 1] and the voltage control 1 helangister Q5 function to change the charging/discharging time constant of the triangular wave output according to the output voltage, thereby controlling the pulse width. . In other words, due to its constant voltage property, the linear die Δ-do Z1 detects a change in the output voltage 11 as a change in current, and operates transistors Q1 to Q5.

However, the Zener voltage must be changed depending on the temperature, and temperature changes in the two-way voltage are treated as fluctuations in the output voltage, which limits the range of use.

Moreover, since it is completely self-excited, there is no need for an auxiliary power supply.
