Abstract
A switching circuit includes a first switching element that has a first control terminal, a connection state between a power generation element and an electric storage device being controlled in accordance with a voltage applied to the first control terminal, and a control circuit configured to output a first voltage to the first control terminal until a voltage difference between both ends of the electric storage device becomes a first predetermined value larger than an initial state when the voltage difference increases from the initial state with time, and output a second voltage to the first control terminal until the voltage difference becomes lower than a second predetermined value smaller than the first predetermined value when the voltage difference exceeds the first predetermined value, the first voltage being a voltage that keeps the first switching element on, the second voltage being a voltage that keeps the first switching element off.
