摘要
本論文之研究主題為設計正負脈衝電池充電法，以較大的正負脈衝電流對電池充電，加快電池充電時間，並利用負脈衝放電電流回復極板間的電解液濃度，之後設置休息時間，以使充電效應得以均勻化。此方法可以抑制電池的充電溫度上升，提升充電效率及延長電池壽命。在文中利用微控制器控制單級返馳式隔離式轉換器，對電池進行預充電，後對電池進行大電流正脈衝快速充電，並利用C-MOS功率開關串聯電阻做為負脈衝放電，加速化學反應，最後階段進行定電壓充電使電池充電的更加飽滿。本電路以實現正負脈衝電池充電器，改變正脈衝和負脈衝的責任周期，量測電池溫度和充電時間，藉此了解正負脈衝電池充電器對電池快速充電之影響。

Abstract
The main research topic of this paper is to design the positive and negative pulse battery charger. Positive/Negative pulse battery charger use a high positive pulse current to charge battery quickly and a negative pulse current to restore the electrolyte concentration between the battery plates. Set the rest time to be homogenized of the charging effect behind the positive and negative pulse current. This method can inhibit the battery charging temperature rise, improve the charging efficiency and extend battery life. In this paper, the use of microcontroller control single-stage isolated flyback converter. First stage, the battery pre-charge, after the battery for high current positive pulse fast charge. Use of C-MOS power switch series resistances as a negative pulse discharge, accelerate the chemical reaction of battery. The final stage uses a constant voltage charge to make the battery charge more full. The circuit to achieve positive/negative pulse battery. To understand the positive/negative pulse battery charger on the battery charger quickly, change the duty cycle of the positive and negative pulse and measure the battery temperature and charge time.
