Abstract: Disclosed is a system for tracking a maximum power point. The system includes an energy harvesting device, a power management integrated circuit including a switching circuit that adjusts an input voltage that is transmitted from the energy harvesting device and a conversion circuit that converts the input voltage adjusted by the switching circuit to output an output voltage, and a measuring device that calculates a ratio of a second power based on the input voltage to a first power based on an open circuit voltage of the energy harvesting device, using an internal impedance of the energy harvesting device and an input impedance of the power management integrated circuit.
