Abstract

PURPOSE: To obtain a stable voltage to be supplied to a halogen lamp by using a voltage regulating circuit to increase or decrease a voltage nearly proportional to an output voltage corresponding to an increase or decrease in frequency of a commercial alternating current.
CONSTITUTION: Commercial alternating-current power 2 applied from power terminal 1 is controlled by thyristor circuit 3, whose ignition phase is controlled by phase control circuit 12, to send needed output voltage 4 out. This voltage 4 is rectified 8 via transformer 6, the rectified voltage is sent to proportional circuit 10, and a proportional output voltage is negatively fed back to circuit 12. Then, voltage regulating circuit 60 is interposed at the part of line 7 following transformer 6 so as to increase or decrease a voltage nearly proportional to the output voltage corresponding to an increase or decrease in frequency of the commercial alternating current. Consequently, the stable supply voltage of a halogen lamp can be obtained without reference to fluctuations of the frequency of the commercial alternating- current power source.
