本論文旨在研製應用於微電網電池充放電系統之雙向直流-直流轉換器之並聯模組，此並聯模組可對電池組進行充放電，並以數位控制實現充放電策略及利用CAN通訊實現均流控制。電路由兩級雙向直流-直流轉換器組成，電路之架構前級採用全橋串聯諧振轉換器，後級採用交錯式降/升壓型轉換器，其操作原理與設計考量皆於本論文中詳細探討。最後實作完成一台18.8kW之雙向隔離型直流-直流轉換器模組。

This thesis aims to study and develop a bidirectional DC-DC charger/discharger converter module for battery charger/discharger systems. This module can be parallel and the digital controller is used to realize charging/discharging strategy and current sharing with CAN. The prototype circuit consists of two-stage bidirectional DC-DC converters. The first and second stage employ Series Resonant Converter and interleaved buck/boost respectively. Operating principles and design considerations are discussed in detail. A 18.8kW prototype converter module was implemented.
