技術簡介

能源收集晶片含直流-直流轉換器及最大功率追蹤演算功能之技術,在常溫下利用人體皮膚溫度與環境溫度差,即可將15mV輸入電壓提升至一般應用系統晶片的1.2V以上電壓。核心技術採用輸出電壓偵測達到最大功率追蹤,極低的能量消耗、最大功率點快速追蹤、以及高效率轉換,使熱電能源轉換系統維持在最佳的操作點。適合生醫、家庭、工業感測及物聯網能源供應,及非常難以取得電源之自然發電能源供給。

Abstract

The energy harvesting power management is including a DC-DC step-up converter and a maximum power point tracking (MPPT) algorithm and boost voltage from 15mV to 1.2V or more. This energy harvesting technology monitors the output voltage to achieve MPPT and optimize operating condition. That features are extreme low power, fast power point tracking, and high efficiency. The proposed suits about supply biomedical, home, industrial sensors, and internet of things power from temperature different between the environment and human skin or anywhere.
