SYSTEM AND METHOD OF MEASURING MAXIMUM POWER POINT TRACKING EFFICIENCY

摘要

The system for tracking the maximum power point according to an embodiment of the present invention is an energy harvesting element, a switching circuit for adjusting an input voltage transmitted from the energy harvesting element, and an output voltage by converting the input voltage adjusted by the switching circuit. Using the power management integrated circuit including the output conversion circuit, and the internal impedance of the energy harvesting device and the input impedance of the power management integrated circuit, the input voltage for the first power based on the open circuit voltage of the energy harvesting device is And a measurement device that calculates a ratio of the second based power.
