Abstract
A constant-voltage power supply circuit includes a first output device provided in a first power feed line from a dc power supply to a first load. The first output device includes a first voltage control element for controlling an output voltage to the first load. A first control device operates for detecting the output voltage from the first output device to the first load, and controlling the first voltage control element to equalize the output voltage from the first output device with a first predetermined constant voltage. A second power feed line is connected to the first power feed line for feeding electric power to a second load. A second output device provided in the second power feed line includes a second voltage control element for controlling an output voltage to the second load. A second control device operates for detecting the output voltage from the second output device to the second load, and controlling the second voltage control element to equalize the output voltage from the second output device with a second predetermined constant voltage.
