Abstract
Disclosed is an energy harvesting apparatus. The energy harvesting apparatus includes a rectifier for rectifying an alternating current (AC) voltage supplied from an energy source into a direct current (DC) voltage, a charging unit for storing an output voltage of the rectifier, and a maximum power point tracker selectively connected between the rectifier and the charging unit, for differentiating the output voltage of the rectifier in a first connection state, and for controlling the output voltage of the rectifier based on a differentiation result.
