Abstract:	本研究的重點在設計一個新穎直流對直流轉換器，應用於太陽能供電系統(如太陽能面板)中，藉由其內部Switch (SW)的切換與儲能的功能，使系統輸出能量可達到動態分配自鎖輸出功率。採用本設計的優點首先是可解決現有太陽能發電系統的材料老化影響效率問題。本系統的運作過程中藉由其自動動態分配自鎖功能，可使系統自動彌補老化造成的衰退效率。其次，若太陽能供電系統部分被烏雲或物影遮光，而影響整體輸出功率，可藉由系統在合成過程中採用動態分配達到最佳輸出功率。另外，太陽能面板內部如因部分電池損壞，產生電流內流造成能量損失，溫度會異常的上升。而採用本設計時，則系統內部每個太陽能電池單元可個別獨立輸入DC/DC轉換器，來達到分擔輸出功率的負載，以及降低工作溫度而減少損耗。最後，因為此分權獨立的方式完全是藉由硬體的組合，不用 DSP(Digital Signal Processor數位訊號處理器)、不需龐大運算器增加成本，隨著系統的擴充與改變仍然是由系統的硬體進行做切換的控制，在應對負載的改變時，系統可以立即做輸出能量的動態分配與處理。 ;The focus of this study is to design a novel DC/DC convertor for Solar energy generation system (e.g. solar panels) that applies its built-in switch and an energy storage functions to achieve a system that offers dynamic allocation and self-locking of the output power. The first advantage of using this novel design is to overcome the decayed output efficiency of a solar energy generation system due to the common material aging phenomena. This newly invented DC/DC convertor can automatically recover its output power efficiency from an already inefficient and decayed solar-panel device. Secondly, if the solar panel is blocked from sunlight and hence induce a lower output power, this DC/DC convertor can utilize its dynamic allocation property to achieve the system’s maximum output efficiency. In addition, if a solar panel suffers partial damage to its internal cell, the internal circuitry will experience unwanted energy loss accompanied by abnormal temperature rise that may further damage the entire system. However, dynamic allocation design enables the power generated by individual solar-cell unit to be transferred into the DC/DC convertor independently. Therefore, the total loading of the output power is shared amongst each cell and hence reduce the overall power loss caused by overheating. Finally, the aforementioned independent weighting allocation function and self-locking mechanism is accomplished entirely utilizing hardware design and not by the Digital Signal Processor (DSP), and therefore, there is no need for a costly CPU. As the system change and upgrade overtime, this switch control function is still based on the system’s hardware. When the device’s loading fluctuated, this system will be able to respond and dynamically allocate the output powder.
