準安定化される所謂クロスレギユレーション方式におい
てオペアンプを用いて負出力の極性を反転させて正極と
し該反転出力をパルス幅制御部に帰還させる事を特徴と
する負出力電圧安定回路。In the so-called cross regulation method in which the positive and negative forces are indirectly quasi-stabilized by electromagnetic coupling between the transformer windings, an operational amplifier is used to invert the polarity of the negative output and make it the positive polarity, and the inverted output is sent to the pulse width controller. A negative output voltage stabilizing circuit featuring feedback.
