Abstract:
1. A power supply apparatus, comprising: a first switch configured to change over electric connection to an electric power generation section; a voltage sensor configured to acquire a magnitude of an input voltage; a control section configured to control the first switch in response to an input from the voltage sensor; a voltage conversion circuit configured to convert the input voltage into a desired output voltage and output the output voltage, wherein, when the input voltage is lower than a voltage required for starting the voltage conversion circuit, switching on and off of the first switch is repeated until the input voltage reaches the voltage required for starting the voltage conversion circuit; and a second switch configured to change over electric connection between the electric power generation section and the voltage conversion circuit, wherein the second switch is switched on after the input voltage reaches the voltage required for starting the voltage conversion circuit.
