Abstract

For example, an averaging circuit includes first to third capacitors and a controller. The controller causes a first first-stage average voltage to be applied to a first capacitor, the first first-stage average voltage being an average of a first voltage applied to the first capacitor and a second voltage applied to a second capacitor, causes a second first-stage average voltage to be applied to the second capacitor, the second first-stage average voltage being an average of a third voltage applied to the second capacitor and a fourth voltage applied to a third capacitor, and causes a first second-stage average voltage to be applied to the first capacitor, the first second-stage average voltage being an average of the first and second first-stage average voltages applied to the first and second capacitors.
