Abstract

PURPOSE: To improve stability, by mounting even a loop to the fluctuation of input voltage to a switching regulator of a single feedback loop for feeding back the fluctuation of output voltage.
CONSTITUTION: Output obtained by turning input voltage Vi ON-OFF at a switching portion 1 is smoothed by a smoothing circuit 3 through a transformer 2 and output voltage Vo is fed to a load 5. The duty ratio of the ON-OFF of the switching portion 1 is controlled by feeding back the fluctuation of the output voltage through a feedback circuit 4, thus constantly controlling output voltage Vo. An input voltage fluctuation correction circuit 6 is mounted, and the duty ratio of the ON-OFF of the switching portion 1 is corrected so as to eliminate effects to the output side by the fluctuation of input voltage Vi, thus reducing the feedback quantity of an output voltage correction feedback loop, then obtaining high stability constant-voltage output.
