移動裝置及無線感測器近年發展快速且未來將會更廣泛被使用，為了延長移動裝置及無線感測器的電池使用時間及滿足嚴苛的負載需求，需要高效率、快速響應的電源管理積體電路。透過將光伏模組與該些應用整合之光能獵能是一方法更進一步，延長電池使用時間或甚至使其能源自主，形成一光能獵能系統。
為了檢驗光能獵能系統的效能表現，光伏模組及光能獵能器皆須被測試及量測，太陽能陣列模擬器及太陽光能模擬器為普遍使用的儀器，以準確及多功能為特色，然而很貴重且難以攜帶。此論文提出一測試環境建置，以一展示箱及其周邊配件建置室外及室內光源之環境，其可調的光源功率密度涵蓋廣泛的應用範圍，此展示箱能以足夠的精準度、較低成本及更佳的可攜性來測試及量測光伏模組及光能獵能器。為了驗證此展示箱的可行性，此論文互相比較以不同方式量測光伏模組及光能獵能器之結果，並說明量測結果間的差異。
提出之展示箱以足夠的均勻度模擬室外光源之功率密度從0到1,999W/m2，模擬室內光源之功率密度從0到20,000 lux，此外，它僅佔20cm × 20cm × 20cm的大小，重量輕，方便攜帶。另一方面，此論文之光能獵能系統包含一光能獵能器及一直流直流降壓轉換器，從先前文獻採用之光能獵能器在快速照度變化的情況下具高效率及快速暫態響應，採用以電流態控制及快速負載暫態響應技術之直流直流降壓轉換器則以較低之電感值重新設計以使負載暫態響應更進步。

Mobile devices and wireless sensor nodes (WSNs) have been rapidly developed in recent years and will get used much more widely in the future. To extend battery usage time of mobile devices and WSNs and to meet their strict load demand, high-efficiency and fast-transient power management IC is needed. Light-energy harvesting is an elegant solution by integrating photovoltaic (PV) devices into such applications to further extend battery usage time or even make them autonomous, forming a light-energy-harvesting system.
To examine the performance of the light-energy-harvesting system, both PV devices and light-energy harvesters should be tested and measured. Solar array simulator (SAS) and solar simulators are widely used instruments with accurate and multifunctional feature. Still, they are expensive and hard to carry. In this thesis, test environmental setup is proposed using a demonstration box with peripheral components to setup both outdoor- and indoor-light environment with controllable power density of the light sources within wide application range. The demonstration box can be used to test and measure PV devices and light-energy harvesters with enough accuracy, lower cost, and better portability. To verify its availability, measurement result of PV devices and light-energy harvester using different ways are compared to each other with elaborated reasons for measurement differences.
The proposed demonstration box models outdoor-light condition with power density from 0 to 1,999W/m2 and models indoor-light condition with power density from 0 to 20,000 lux with enough uniformity. In addition, it only occupies size of 20cm × 20cm × 20cm with very-light weight, featuring great portability. On the other hand, the light-energy-harvesting system in this thesis contains a light-energy harvester and a DC-DC buck converter. The adopted light-energy harvester from previous work features high efficiency and fast-transient response under fast-irradiance-changing condition. The DC-DC buck converter employing current-mode control and fast load-transient technique is re-designed with lower inductance to further improve the load-transient response.
