電磁感應發電儲能裝置之設計與測試

Abstract

本論文設計出電磁感應發電裝置，其原理為利用線圈在磁場中直線運動因電磁感應而產生電壓，並經過儲能電路系統將能量收集到儲能元件中。儲能電路系統可分為整流器和直流對直流轉換器兩個部分。直流對直流轉換器這裡選擇使用升壓轉換器，升壓轉換器的功能為將電壓提升到儲能元件的工作電壓，使其能順利充電。為了使線圈有最佳的輸出功率，升壓轉換器的設計上要考量到最佳阻抗匹配，將升壓轉換器等效成一個阻抗，使其和發電線圈互相匹配，得到最佳輸出。此外升壓轉換器也考量了轉換器中各個電子元件的耗能，並使其操作在耗能最低的狀態，以提高其效率。

This paper presents an electromagnetic induction generator. Voltage generated by electromagnetic induction coil is attributed to linear motion in a magnetic field. Power from electromagnetic induction generator is transferred by harvest circuit to the energy storage device. The whole harvester circuit includes rectifiers and DC to DC converter. A boost converter is used in this paper. The function of boost converter could raise voltage so that the voltage of generator will reach to operating voltage of energy storage device. In order to make optimum output power, optimum impedance between power generator and boost converter is considered. The boost converter is equivalent to a resistor to match the coil. In addition, the energy consumption of each electronic component of the boost converter is considered in this paper to enhance its efficiency.
