近年來，電動車被視為分佈式電源，用於存儲電力並將電力送回電網，但電動車儲能系統需能夠以雙向功率傳輸運行。本論文旨在研製應用於電動車儲能系統之交錯式雙向CLLC諧振轉換器，此拓撲架構由兩組轉換器以開關訊號錯相90度的方式並聯，轉換器輸出直流電壓可通過頻率調變控制(PFM)進行電壓調節。本轉換器同時擁有以下特點:(1)對稱性架構，具有雙向功率傳輸特性，並且在雙向功率傳輸時功率開關皆具柔性切換；(2)使用交錯式技術，降低輸出電流漣波，並增加功率及穩定性；(3) 利用不對稱脈波調變(APWM)，限制輸入功率以解決並聯時因諧振槽存在差異而產生負載分配不均的問題。本論文完成一適用於電動車儲能系統之直流-直流轉換器，其特性具雙向功率傳遞、具低輸出電流漣波與具負載平衡等特色。最後本論文研製出輸入直流電壓350V、輸出電壓為可調範圍280V~400V且最大功率1000W之直流-直流轉換器，經實驗結果得出其順向充電模式最高效率可達92.4%，反向放電模式最高效率亦有92.3%。

In recent years, electric vehicles have been viewed as distributed power sources for storing electricity and sending it back to the grid, but electric vehicle energy storage systems need to be capable of operating in bidirectional power transmission. The purpose of this thesis is to develop an interleaved bidirectional CLLC resonant converter for electric vehicle energy storage systems. This topology is connected in parallel by two sets of converters with phase-shifted switch by 90°. The converter output DC voltage can be voltage-regulated by frequency modulation control. The converter also has the following features: (1) Symmetrical architecture with bidirectional power transfer characteristics, and soft switching of power switches during bidirectional power transfer; (2) Use of interleaved technology to reduce output current ripple and increase Power and stability; (3) The asymmetric pulse modulation method is used to limit the input power to solve the problem of load sharing due to the difference of the resonant tanks in parallel. This paper completes a DC-DC converter for electric vehicle energy storage system, which features bidirectional power transmission, low output current ripple and load balancing. Finally, a DC-DC converter with an input DC voltage of 350V and an output voltage of 280V~400V and a maximum power of 1000W is developed. The experimental results show that the maximum efficiency of the charging mode can reach 92.4%, and the maximum efficiency of the discharge mode is also 92.3%.
