本文以應用於太陽能模組之新型雙向直流升降壓轉換器設計為研究目標,系統架構包含:太陽光電池、新型雙向直流升降壓轉換器、鉛酸電池與微控制器。 由於現今全球工業的高度發展,造成環境污染與能源短缺的問題日益嚴重,因此開發再生能源勢在必行,其中太陽能為頗受各界重視的再生能源之ㄧ。轉換器為太陽能應用中不可缺少的一部份,轉換器可以有效轉換太陽能光電板所收集到的能量,並使其應用範圍更加廣泛,加速太陽能在全球的推廣。系統主電路為新型雙向直流升降壓轉換器,並以微控制器來管理和控制,它具有充電器和放電器的結合功能,並兼有穩壓控制及定電壓充電控制的功能。 最後製作出應用於太陽能模組之新型雙向直流升降壓轉換器電路,經由模擬和實測,而驗證其可行性。
In this thesis, the design of a novel topology of bidirectional buck-boost DC/DC converter for photovoltaic module is the study objective. The system architecture includes solar cells, novel topology of bidirectional buck-boost DC/DC converter, lead-acid battery and a single-chip microcontroller (PIC). Due to high degree global industrialization, environmental pollution and energy shortages are becoming serious problems in nowadays, therefore it is imperative to develop renewable energy. In a variety of renewable energies, solar energy is one of the most attractive selections. Converters are absolute necessity for solar power applications. This thesis presents a novel topology of bidirectional buck-boost DC/DC converter which can manage and control both of charging and discharging functions for using in a solar cells system. Finally, through simulation and experimental measurement, this design has been verified.
