自主性轉換電路設計與應用

「自主性轉換電路系統之設計與應用」本文研究採用自主式之判斷法則切換，其自主性轉換電路系統利用電壓差的判別型式來達成自主性的切換。此系統切換模式分為供電模式(supply)、充電與供電模式(charge and supply)、及混合供電模式(hybrid)，有別於傳統電路系統需經過整流電路將交流電轉成直流電後，再經由感測器和切換開關進行判斷。本研究係以壓電材料攫取能源為例，由於壓電材料本身產出的能量很小，若使用整流電路則會損失大量能量於整流電路轉換過程，因此本論文採用了堆疊電路(stack circuit)來提升壓電材料所產生的電壓準位，進而取代整流電路以減少能量損失，適用於小電源之能量轉換。研究內容主要包括自主性壓電發電轉換電路系統及其架構研究探討，並針對所設計之堆疊電路、直流昇壓型電源轉換器(DC-DC Converter)、混合式供電模式電路等，實驗驗證其功能。本研究之自主性轉換電路系統相較於舊式使用MOSFET切換電路系統可節省28.6%之消耗能量。

"Autonomous conversion circuit system design and application" is used to determine the autonomous switching rule, using voltage difference to achieve self-determine the type of switching. The system is divided into switch mode power supply mode (supply), charging and power supply mode (charge and supply), and mixed power mode (hybrid), distinct from the traditional that using rectifier circuit to convert AC into DC, through sensors and switches to judge. In this study, piezoelectric materials to capture the energy, for example, due to the energy output of the piezoelectric material itself is very small, the use of rectifier circuit will be a significant loss of energy conversion process in the rectifier circuit, so this thesis uses a stack circuit to enhance the piezoelectric material generated voltage and replace rectifier circuit to reduce energy loss for small power of energy conversion. In this thesis, autonomous piezoelectric power conversion circuit system and its architecture is studied. Design of the stacking circuit, DC boost power converters (DC-DC Converter), and hybrid power mode circuit are examined with experimental test. In comparison with the general power conversion circuit using MOSFET switching circuit, the proposed autonomous system in this study can save 28.6 percent of the consumption energy.
