係してくるのは入力電圧の変動であることから・上記■
の形式を採る場合が多い。A switching regulator is a so-called DC-DC converter, which converts the secondary side DC input into AC using PWM control (pulse width modulation control), and then outputs it to the secondary side via a transformer tube at various required levels and stabilizes it. It is used to obtain various types of DC output. Stabilization in this case is achieved by the above-mentioned PWM control.In general, there are two types of control for multiple output switching and switching regulators: (1) monitoring only input voltage fluctuations, and (2) monitoring only output voltage fluctuations. ■
There are two types of monitoring methods: those that monitor both input voltage and output voltage fluctuations; however, since input voltage fluctuations are usually most closely related to the stabilization of DC output,
It often takes the form of

The idea is to make the width narrower, and as it descends, the width becomes wider. For this reason, there is no stable point for stabilization, and it is floating. As a result, the sui has high stability.

If the peak level of the voltage of the AC signal fluctuates in height, 1! The pulse width is controlled to be narrower or wider. In this way, the AC signal, which has been stabilized to a certain extent by the feed forward control, passes through the transformer 10, and the DC outputs, which are stabilized to some extent and at the desired level, are output. 6 rectifier circuits 19, 19'

It cannot be said that the stabilization of t + DC6ut has been sufficiently achieved. Because - Feed Forward, not Feed Pack City 1j#? ! This is because the pace is based on II flil. Therefore, in order to eliminate such feed-forward control, the above-mentioned detection winding 13 is provided. This detection circuit is wound on the same core of the transformer 10.

However, the diode D is a half-wave rectifier diode, the resistor R1 is a shunt resistor for absorbing surge l, and the resistor R2 is a resistor for level adjustment, which are not particularly essential parts of the present invention, and are therefore not related to the present invention. This is a CR time foot count circuit 21 connected to the Fi detection winding 13 of . When the waveform twm shown in FIG.
