摘要

PROBLEM TO BE SOLVED: To solve a problem that the operation frequency of a switching element of an inverter circuit in a power supply device interferes with or hinders specific frequencies of other radio equipment or facilities.SOLUTION: A power supply device 1 has an inverter circuit which contains an inductor for radiating supply power and a switching element, and outputs the supply power to the inductor, and a control circuit for controlling the inverter circuit at an operation frequency of the switching element which is set to a frequency which is deviated from the operation frequency of other radio equipment or other facilities by only a predetermined frequency.SELECTED DRAWING: Figure 1
