Claim:
1. A power supply apparatus that receives electric power from a power generation apparatus having a varying output and supplies electric power to an outside, the power supply apparatus comprising: a power storage device that has a larger amount by which electric power is stored and/or a lower self-discharge rate than a capacitor device used as a passive device and also has higher charge and discharge efficiency and/or higher responsiveness than a secondary battery, the power storage device receiving electric power from the power generation apparatus and discharging electric power to the outside; a current control unit that controls a current supplied from the power storage device to the outside; and a control unit that controls a current and a voltage of the power generation apparatus by charging and discharging the power storage device, so as to maximize an amount of power generation by the power generation apparatus, wherein the power supply apparatus comprising: a first to an n-th power storage devices, wherein n is a natural number larger than or equal to 2, wherein the first power storage device is connected in parallel to a first power generation apparatus, the n-th power storage device is connected in parallel to a n-th power generation apparatus, the first to n-th power storage devices are mutually connected in series, and the first to n-th power generation apparatuses are mutually connected in series through a diode.
