Abstract:
1. A load driving circuit that applies a voltage to a load to drive the load, comprising: a plurality of first storage elements that are charged by receiving a supply of voltage from a power supply; a series storage element group constituting unit that switches a connection state between the plurality of first storage elements to constitute a series storage element group in which the first storage elements are connected in series; a second storage element charging unit that charges a second storage element different from the first storage elements using the series storage element group; and a voltage applying unit that switches between a first connection state and a second connection state to apply a voltage to the load, the first connection state being a state in which the charged second storage element and the series storage element group are connected to the load while the second storage element and the series storage element group are connected in series, the second connection state being a state in which the series storage element group is connected to the load while the series connection between the second storage element and the series storage element group is broken.
