本實驗室所開發之功率調節器是適用於分散式太陽能發電系統，先前的研究大多集中在功率調節器電路設計與相關操作問題，所以設計時也讓功率調節器的安全係數提高，採用的電路元件也較高價，同時本身也有些數值量測的問題，所以本研究的功率調節器採用了先前的升降壓變壓器設計(Buck-boost)設計，修改了裡面的電路元件及微處理器程式，增加功率調節器的穩定性及製造成本。
第二部分則是熱傳分析，太陽能電池高功率輸出時，功率調節器上電路元件會有高溫的現象，就會提高功率調節器損壞的機率，所以用ANSYS Fluent模擬現實在高功率條件下功率調節器的溫度，選用適當的散熱裝置”熱導管”取代先前的散熱貼片，再進行熱導管及搭配其他散熱裝置的模擬，模擬出功率調節器增加熱導管及其他散熱裝置的散熱效率，在跟實際的功率調節器做系統整合測試，印證熱傳分析的可行性。
最後設計出可以跟功率調節器跟熱導管完美結合的接線盒，藉由熱傳分析給人在功率調節器安裝散熱裝置的建議，以及規劃出一個完整的太陽能發電系統。

The laboratory has developed the photovoltaic power optimizer which is suitable for distributed solar power system. Previous studies mostly concentrated in the power optimizer circuit design and related operation problems. And they choose to use higher price of circuit element, let the safety factor be higher. I also find some problems of measurement. So this study uses previous photovoltaic power optimizer (buck-boost converter) design, modifies the circuit components and microcontroller programs to increase power optimizer stability and reduce the manufacturing costs.
The second part is the analysis of heat transfer. When the solar panel has high-power output, the circuit elements in the power optimizer have a high temperature phenomenon. It will increase the chance of damage for the power optimizer. I use ANSYS Fluent to simulate the real temperature conditions of power optimizer at high-power output. I use the appropriate cooling device "heat pipe" instead of the previous heat sink. And then I combine with the heat pipe and heat sink to make the circuit elements much cooler in the power optimizer. I also the simulate temperature conditions of the power optimizer with the heat pipe and other heat sinks. To prove the heat transfer analysis of feasibility for the real power optimizer actual and cooling device.
I finally design a junction box which can perfectly combine the heat pipe and the photovoltaic power optimizer. I can prevent the power optimizer from thermal damage. I can also give a suggestion to install the cooling device by thermal analysis.
