交直流轉換電池充電機
指導老師:賴慶明   組長:曾韋翔   組員:曾韋翔
主要是探討日常生活中隨處可見的電池充電機,不論是什麼樣的產品,只要用到充電電池,其源頭就有一個交直流轉換的變壓器,透過交流轉換成直流並且降壓,使電壓轉換成可以對電池充電的形式。
利用以LM338T為主,根據其Datasheet配置電路的電容、電阻,探討其原理及操作方式,以達到所求之電壓、電流;最後實際操作並且記錄數據。
This paper presents a circuit structure of an AC/DC Convertor Battery Charger. There is an AC/DC convertor at the source when there is a rechargeable battery involved in a product. To charge the battery, the alternating current is transformed into direct current and step-down from 110V to 15V through the convertor.
The paper use IC LM-338T to be the main component. Capacitors and resistors are mated according to a constant voltage control circuit of the datasheet of LM-338T. Discuss the theory and operational approach to achieve the expected voltage and current. At last, record the experimental data and plot curves to show the relation between voltage, current and battery.
我們決定將壓電陶瓷晶片和鞋子做結合。
