Abstract
Official abstract text for this publication.
A voltage conversion circuit has a plurality of primary capacitors charged by a power supply, a secondary capacitor connected in parallel to the respective plurality of primary capacitors that is charged at a voltage supplied to a load circuit, a plurality of switching circuits provided in association with the respective plurality of primary capacitors that change over a connection state between the primary capacitors and the secondary capacitor, and a connection control circuit that successively connects the respective primary capacitors to the secondary capacitor through the corresponding switching circuits, the respective primary capacitors across which the charging voltages reach a predetermined connection voltage higher than a charging voltage across the secondary capacitor.
