Abstract

PURPOSE: To easily and effectively stabilize each output, by performing double control for two outputs through a single control loop.
CONSTITUTION: Power E is applied to input terminals 1, 1'. A transistor 5 is opend and closed to intermit the current flowing through the primary winding of a transformer 4. A voltage generated by the secondary winding of the transformer is smoothed into a DC voltage to energize a load 14. The error in a voltage between terminals 2, 2' is detected by a control circuit 9. An output resulting from the detection is applied to a pulse generator 8 to control the on/off ratio of driving pulses to stabilize the first output voltage. The error in a voltage between other terminals 3, 3' is detected by another control circuit 9'. An output resulting from the detection is applied to the pulse generator 8 to control the frequency of its driving pulses to stabilize the output voltage of the pulses.
