Abstract

There is disclosed a power supply system comprising capacitors that are connected switchably via a small number of switches to decrease variations of an output voltage. The switches comprise a series connection switch and first and second sets of switches. A control means controls the first set of switches, the second set of switches, and the series connection switch to switch connection of the capacitors of the first and second sets among a first state in which the first set of capacitors is connected in series with the second set of capacitors, a second state in which the first set of capacitors is connected in parallel with the second set of capacitors, and a third state in which one or more capacitors of the first set are connected in parallel with one or more capacitors of the second set.
