本文以德儀的數位訊號處理器TMS320LF2407為控制核心，控制三台雙向直流/直流功率模組，以軟體程式實現自動主僕均流法，研製雙向並聯功率模組，確保每一部電源功率模組能均勻地分擔負載電流。當市電正常供電時，由系統匯流排端對電池端充電，若電池電量不足時，雙向轉換器以定電流對電池進行充電；若電池電量充足時，雙向轉換器以定電壓對電池進行浮充。當市電端斷電時，由電池提供能量給系統匯流排端，以提供能量給負載。實驗結果顯示本文所使用之並聯均流技術其均流誤差率均維持在 5%之內，電壓調整率為0.26%。在負載變動期間，每一部電源模組亦能均勻地提供能量給負載。另外，透過RS-232傳輸介面，在電腦端以Visual Basic撰寫一監測程式和DSP建立通訊，使各個功率模組的電流值、輸入電壓、輸出電壓、電池溫度等資料，能即時顯示於螢幕上，以方便使用者做即時的監測。

　In this thesis, DSP-based paralleled bidirectional dc/dc converters are designed and implemented. By using TI TMS320LF2407 DSP and automatic master-slave current-sharing technique, the converters can equally share the load current. In normal operation, the converters supply energy from system bus terminal to battery terminal. When the residual capacity of battery is insufficient, the converters charge battery with constant current. When the residual capacity of battery is sufficient, the converters charge battery with constant voltage. In utility power failure condition, the converters are operated in the discharge mode, that energy is transferred from battery terminal to system bus terminal. The experimental results show that the current-sharing error is within 5% and voltage regulation is 0.26%.
　In addition, the communication between computer and DSP is implemented via an RS-232 interface. By using the Visual Basic real-time monitoring program, the currents of three converters, input voltage, output voltage and the battery temperature are displayed on the remote monitoring system.
