Abstract
A power supply circuit according to an embodiment of the invention includes: voltage sources; voltage control circuits that boost an input voltage; and a voltage source connection switch that connects at least one of the voltage sources to one of the voltage control circuits. For example, the voltage source connection switch connects, to the voltage control circuit, a voltage source having a voltage lower than a predetermined reference voltage among the voltage sources, and connects, to the voltage control circuit, a voltage source having a voltage equal to or higher than the determined reference voltage among the voltage sources.
