MAXIMUM POWER POINT TRACKING CIRCUIT GENERIC TO A VARIETY OF ENERGY HARVESTER DEVICES

摘要

A maximum power point tracking circuit for an energy harvester device, the tracking circuit requiring nanoampere current in a standby mode, includes a maximum power point circuits utilizing a predetermined fraction of the open circuit input voltage to determine the maximum power point for energy harvester device. A circuit determines the predetermined fraction of the open circuit voltage of the energy harvester device. A sample and hold circuit measures and holds him the predetermined fraction of the open circuit voltage of the energy harvester device for use by the maximum power point circuit
