隨著電動車及家用儲能設備的需求，直流電網與儲釋能設備之間的電能處理將顯得更重要。本文提出並實現一應用於電池系統之雙向CL3C全橋諧振式轉換器，以雙向主動橋式轉換器為主要架構，並改善傳統LLC諧振轉換器，將二次側新增一諧振電感與一諧振電容，形成雙向CL3C諧振轉換器，在雙向操作下皆可實現電源側功率開關之零電壓切換與整流側零電流切換，提高整體電路效率，並解決雙向LLC諧振轉換器於反向操作時諧振槽無法升壓之問題，利用變壓器將提供電氣隔離功能增加電源使用之安全性。本文利用數位控制技術控制電能轉換，以仿效之直流電網對電池以CC-CV充電，並且可再操作電池釋能回仿效之直流電網達到能量雙向轉換之目的。最終在充電模式下以仿效之直流電網電壓為400V對電壓範圍為280V~403V之電池進行CC-CV充電，最大充電功率為2015W，最高效率可達96.64%；在釋能模式下以電壓範圍為280V~403V之電池對直流電網進行釋能，最大釋能功率為2kW反向放電回直流電網最高效率可達95.79%

Due to the requirements of electric vehicles and household energy storage equipment, the energy processing between the DC grid and the energy storage equipment will become more important. In this paper, a Bidirectional CL3C Full-Bridge Resonant Energy Storage Converter is developed. By integrating circuit structure of the active bidirectional bridge with resonant technique, the proposed bidirectional CL3C resonant converter will address the unit gain problem of the LLC resonant converter in the reverse mode. The bidirectional CL3C resonant topology is realized, the switches at primary side have zero voltage switching function, and the switches at the secondary side have zero current switching is respectively. It helps to increase the bidirectional power conversion efficiency. The transformer with isolation makes the converter safer. By using the digital signal processor as the power control unit, the energy storage battery is able to charge with CC-CV method with the simulated DC grid, and the energy storage battery is able to discharge to the simulated DC grid. The experiment results reveal that the charging mode operation of 400V simulated DC Grid charge to 280V~403V energy storage battery with CC-CV method, the maximum power is 2015W and the maximum efficiency is 96.64%, In the discharging mode operation of 280V~403V energy storage battery discharge to 400V simulated DC Grid, the maximum power is 2000W and the maximum efficiency is 95.79%.
