Abstract
A voltage converting circuit includes a plurality of first capacitors that are charged by a power source, a second capacitor, connected in parallel to the plurality of first capacitors, which is able to be charged to a voltage that is supplied to a load circuit, and a plurality of switching circuits, provided in such a way as to correspond to the plurality of first capacitors, each of which switches states of connection between its corresponding first capacitor and the second capacitor. The first capacitors are sequentially connected to the second capacitor through the corresponding switching circuits as charging voltages of the first capacitors reach a predetermined connection voltage that is higher than a charging voltage of the second capacitor so that the first capacitors are not short-circuited with each other.
