Abstract
PURPOSE: To enable stable action even if the range of input voltage and the range of load change is large, by giving the output of comparator comparing the output of error-amplifying device with triangular-wave voltage to switching circuit through one-shot circuit.
CONSTITUTION: Electric current from power source 1 is supplied for the winding on the primary side of transformer 2 through switching element 3 whose conductivity is controlled by control circuit 9, while from the winding on the secondary side of transformer 2 is supplied electric power to load 5 through smoothing circuit 4. Output voltage Eo and standard voltage Es are inputted in error-amplifying device 6 and its output Ec and the output of triangular-wave generating circuit 8 are inputted in comparator 7. The output thus obtained is inputted in control circuit 9 through one-shot circuit 10 such as monostable multi-vibrator. In addition, the output of one-shot circuit 10 is also inputted in triangular-wave generating circuit, thus the frequency of triangular wave being controlled.
