摘要:	各國為達成減碳政策，進一步加大電動車取代燃油車的力道，另外與此並行的是綠能占比的提升，然而綠能發電因為不穩定的特性需要某些電力調度的能力，電動車所帶來的 V2G能力能夠很好的作為儲能設備來輔助調度，對於提升綠能占比有很大的幫助。 CLLLC常見於雙向電路架構，鑒於文獻缺乏大功率應用的 CLLLC雙向系統， V2G能力也就無法在大功率情形下運用，而未來電池快充站很可能是電動車發展的關鍵，因此本文欲設計一應用於充放電系統的雙向大功率架構，以期 V2G能有更高效的調度能力除了 CLLLC針對大功率需求做設計，並利用可模組化的並聯架構來進一步提升功率容量，也因此加入自動主從控制策略來改善並聯架構的缺點，最後為求貼近實務所需，加入 CC-CV電池充電控制策略，以讓本文開發的電路架構能工作於充放電系統，將利用 Matlab-Simulink來模擬驗證系統實驗結果。;In order to achieve carbon reduction policies, countries have further increased the power of electric vehicles to replace fuel vehicles, and in parallel with this is the increase in the proportion of green energy. However, due to the unstable characteristics of green energy power generation, certain power dispatching capabilities are required. Electric vehicles. The V2G capability brought by it can be used as an energy storage device to assist dispatching, which is of great help to increase the proportion of green energy. CLLLC is commonly used in bidirectional circuit architecture. In view of the lack of CLLLC bidirectional system for high-power applications in the literature, the V2G capability cannot be used in high-power situations. In the future, battery fast charging stations are likely to be the key to the development of electric vehicles. Therefore, this paper intends to design a The bidirectional high-power architecture applied to the charging and discharging system is expected to have a more efficient scheduling capability for V2G. In addition to the CLLLC designed for high-power requirements, the modular parallel architecture is used to further improve the power capacity. From the control strategy to improve the shortcomings of the parallel architecture, finally, in order to be close to the practical needs, the CC-CV battery charging control strategy is added, so that the circuit architecture developed in this paper can work in the charging and discharging system, and Matlab-Simulink will be used to simulate and verify the system. Experimental results.
