By combining the techniques on inductor sharing and bidirectional power converter, the harvesting-and regulating-stage circuits in conventional energy harvesting system can be merged into a single-stage circuit. With the proposed duty-cycle-based strategy for maximum power extraction and the high-efficiency timing scheme for inductor sharing, the proposed multi-input thermoelectric energy harvesting system can ensure optimal power transfer from each thermoelectric energy source without sacrificing power conversion efficiency (PCE) and maximum output power capability. The peak PCE is achieved at 58.5%, the maximum end-to-end output power is 2.43mW, and the maximum output power capability is 32.4mW while the storage capacitor is fully charged. © 2016 World Scientific Publishing Company. |
