微功率輸入之高效率AC-DC電荷幫浦設計

Design of High Efficiency AC-DC Charge Pump for Micro Level Input Power

摘要


隨著社會上對環保與節能觀念的重視,將環境中存在的能量接收並轉化為可用電力的各種獵能技術(Energy Harvesting Technology)逐漸受到關注。本文主要針對目前各種獵能技術中不可或缺的AC-DC電荷幫浦進行介紹。一般而言,由於電荷幫浦中二極體或電晶體的臨限電壓限制,電荷幫浦的高效率操作區大多是數十毫瓦以上的中高功率輸入訊號,但由於各種獵能技術所能擷取到的能量均為微瓦等級的微弱訊號,因此需要針對此應用情境對目前的電荷幫浦進行進一步的研究與設計,使電荷幫浦能夠在微瓦等級的功率輸入時還能保持高AC-DC轉換效率。

Energy harvesting technology is a novel research topic in these years. The energy harvesting circuit can harvest micro-level energy from vibration, RF signal, heat in the environment and provide DC voltage for many applications. In the energy harvesting circuit a charge pump which can convert micro-level AC signal to DC voltage is very important. Generally, a charge pump is design by many diodes or transistors and the AC-DC efficiency will be 50~70% only when the input power is larger than 10 dBm. In order to convert micro-level input power of energy harvesting circuit, we need to research and redesign the charge pump for input power smaller than -10 dBm and try to improve the poor efficiency of charge pump.
