Abstract
Disclosed is a power supply device including a first direct-current power source that generates a direct-current voltage to be supplied to a device that is a load, and a second direct-current power source that generates a direct-current voltage to be supplied to a sensor that detects a physical quantity. The first direct-current power source is an output variable type power source that generates a direct-current voltage that changes according to a signal from the sensor, and the second direct-current power source is an output fixed type power source that generates a constant direct-current voltage.
