Title: Regulated power supply
Inventor: JIERORUDO JIEI ROJIYAASU
IPC: G05F1/56
Filed: 1985-11-19
Abstract: PURPOSE:To compensate the change of an output voltage due to load variation over a wide range and to make a regulated power supply correspond also to the fine transient variation of a DC output voltage by forming two feedback loops. CONSTITUTION:When transient rise exceeding a steady value is generated in the DC output voltage Vo of a power supply, a feedback voltage Vd is increased and the output voltage Va of an amplifier 30 is turned to a negative value. Since the DC output voltage Vo=Vr+Va is formed, the Vo is dropped and compensated in accordance with the drop of the Va. Even if the Vo is increased due to the load variation of the power supply, the Vo is compensated similarly to said case. When the Vo is dropped due to the load variation, the feedback voltage Vd is dropped at first, and then the differential amplifier 30 is operated so that the output voltage Va of the amplifier 30 is increased in the positive direction. The output voltage Vb of an amplifier 40 is increased in accordance with the rise of the Va to compensate the initial drop of the Vo. When the Va is increased, an output voltage Vb from an amplifier 40 is increased, and an peak output voltage of an oscillator 10 is also increased. Consequently, a floating output voltage Vr of a rectifier smoothing circuit 20 is increased.
