近年來智慧型電網的發展備受重視，已有諸多學者為了使電網運作的更有效率紛紛致力於家庭區域電網的研究。本文採用相移式的雙向隔離型直流電壓源對直流電壓源轉換器與磷酸鋰鐵電池來實現家庭區域電網的概念，並利用CAN-bus通訊介面來達成Laboratory Virtual Instrumentation Engineering Workbench (LabVIEW) 圖控軟體與數位訊號處理器之間的溝通，藉由LabVIEW圖控軟體下達電流命令給數位訊號處理器來控制轉換器的運作，以完成對磷酸鋰鐵電池做定電流與定電壓充電以及定電流放電，並針對五種不同的緩衝電容做效率與損失的分析。

In recent years, smart gird has received much attention, and many researchers have devoted to home area network (HAN) to improve the efficiency of grid. This thesis proposes a bidirectional isolated DC-DC converter (Dual Active Bridge, DAB) with phase shift control to implement the concept of HAN. Li+Fe battery is used as storage device of the converter, and a bidirectional communication between Laboratory Virtual Instrumentation Engineering Workbench (LabVIEW) and Digital Signal Processor (DSP) is realized by CAN-bus. By setting the current command given by LabVIEW system, the converter is able to charge the Li+Fe battery with constant current and constant voltage method as well as discharge the Li+Fe battery with constant current. Operation principle of the converter and the associated loss are presented.
