Abstract

PURPOSE: To achieve small size and low cost, by using full wave rectifying circuit in place of transformer and taking current feedback type.
CONSTITUTION: The AC power supply 1 is fed to the load L via the combination circuit 3 between SCR21 and full wave rectifying circuit 3. The fine value resistor 22 in series connection with SCR21 detects the current of the load L and feeds it to the comparison circuit 5 via the smoothing circuit 9. The comparison circuit 5 compares the reference voltage of the reference voltage production circuit 4 with the voltage from the smoothing circuit 9, and the output is given to the phase control circuit 6. The control circuit 6 controls the trigger phase of SCR21. Further, the circuits 4W6 receive power supply via the full wave rectifying circuit 3 and diode 23.
