摘要: 大自然中存在著各種的乾淨且安全的能源,像是潮汐、風力、太陽等等 。使用這些能源不會污染環境也不會傷害人類,並且都是未來電力的主要 來源。本論文的主要目的就是設計具有最佳電力輸出技術之光電池電源, 並且將他驗証在一種新式的交流電力收集網上。 在任意的照度下,光 電池都有一個最佳的工作點使之能產生最大的功率。為了得到這個最大的 輸出功率,光電池通常需要一個有最家工作點追蹤的控制器。本論文就是 利用直流╱直流轉換器來實現這個具有最佳工作點追蹤功能的控制器。這 個控制方法是很容易地實現在真實電路中,而且不論照度如何變化,這個 方法都可以追蹤到最佳工作點。 傳統的直流串並聯網路有很 多的缺點,若是電源內阻設計不良將影響功率的輸出,大大降低了網路匯 集的效果。這裡我們將介紹一種新式的交流電力收集網,他改良了傳統網 路的缺點,並且利用具有最佳電力輸出技術之光電池來驗證他。 The nature fills with many kinds of clean and safe energies, such as ocean wave, wind flow, and solar light etc.. Using these energies will not pollute environment and damage human, and they will be the main energy source in the future world. In this thesis we propose a solar cell current inverter with maximum power point tracking(MPPT) technology and realize this technology in an ac type power accumulation network. In any irradiance, the solar cell has an optimumoperating point to be able to get the maximum power. To obtain the maximum power from a photovaltaic module, the photovaltaic power system usually requires a maximum power point tracking controller. This thesis proposes that how to use the dc/dc converter to obtain this MPPT controller. Therefore, this control method is easy to implement to a real system. Moreover, this method can track maximum power pointrapid even if irradiance changes. The traditiona dc series-parallel network has many drawbacks.If the internal impedance of the power source is unmatched with loads, the output power of power source will be influenced, and decrease the accumulation efficiency of the network. There is a new type ac power accumulation network which is presented in 1997. It can improve many drawbacks in the traditional networks. We will prove this new type ac network using solar cell current inverter with MPPT technology.
