由於可充電電池的使用日益普遍，電池充電技術就益形重要。本文提出一個新型的多模式充電電路，由一個新型的Reflex充電電路，配合一個可控的定電壓，定電流之充電電路發展而成。這個多模式充電電路，不但可以實現定電壓、定電流、脈衝和Reflex四種基本充電模式，更可以實現多種混合的多階段充電模式。本電路可以容易的改變充電模式以及各項充電參數，因此可以作為進一步研究最佳充電方式的工具。
為了達到簡化控制電路，以及提供調整的彈性，本電路使用數位訊號處理器配合感測與介面電路，隨時監測充電電池之電壓與電流的變化，再依據設定的充電策略，調整導通率及輸出電流，切換充電模式，達到多模式充電之目的。
本文已完成一個雛型充電電路，本文的實驗是以鉛酸電池做為實驗電池。實驗結果顯示，這個充電電路確實可執行各種充電模式及混合模式之充電策略。

Charging technology is becoming more and more important since rechargeable batteries are commonly used in many applications than ever before. To facilitate various charging profiles, a battery charger with multi-mode is proposed. The charger is composed of an innovative reflex charging circuit and a controllable half-bridge converter with pulse-width-modulation. This multi-mode charger provides not only four basic functions of constant voltage (CV), constant current (CC), pulsed current (PS) and reflex charging (RX), but also the multi-stage charging with hybrid charging modes. The desired charging profile can easily be accomplished by adjusting the controllable parameters of the charger.
In order to simplify the control circuit, a digital signal processor (DSP) with the associated sensors and interface circuits are used as the control kernel. By continuously monitoring the charging current and battery voltage, the charging modes can be adapted to the charging strategy.
An experimental charging circuit is built and tested. The experiments in this dissertation are carried out on lead-acid batteries, Experimental results show that the charger is able to execute the charging functions of various tentative charging strategies with hybrid charging modes.
