Abstract
A power supply apparatus includes a first circuit, a second circuit, a switcher configured to switch between a power supplied state and a power interrupted state, a driver configured to output a signal for switching the state of the switcher, an adjusting unit, a first control unit, a second control unit, a first communication portion, and a second communication portion. The first control unit is operated by power supplied by a signal generated in the first communication portion. The first control unit transmits, to the second communication portion, information about a detection result. The second control unit controls the adjusting unit based on the information. The first control unit outputs a predetermined signal for causing the driver to output the switching signal for putting the switcher into the interrupted state in a case where abnormality occurs. The driver outputs the switching signal for putting the switcher into the interrupted state based on the predetermined signal.
