Abstract:
A power supply circuit includes: an input terminal; a DC voltage converter that converts a DC input voltage supplied to the input terminal into a DC output voltage; an output terminal that outputs the DC output voltage; a bypass circuit provided to the DC voltage converter between the input terminal and the output terminal; and a monitor control unit that monitors whether or not the DC input voltage satisfies a predetermined condition to be processed in the DC voltage converter, so as to connect the input terminal to the output terminal via the bypass circuit if the DC input voltage does not satisfy the predetermined condition.
