Design of a Hybrid Battery Charger System Fed by a Wind-Turbine and Photovoltaic Power Generators

[[abstract]]本文旨在研製以數位訊號處理器為控制之太陽能及風力能源混合式充電系統。系統由太陽能電池、風力發電機、鉛酸電池、升降壓型直流轉換器所構成。太陽能電池、風力發電機為系統主要電力來源，電池則儲存能量。 由於太陽能電池、風力發電機之輸出功率隨著天氣情況及氣候變化變動甚大，對此利用升降壓型直流轉換器可將輸入之不穩定之電源調整至最適當輸出，並採用數位訊號控制器 dsPIC30F4011 為核心，經由擾動觀察法來控制，並取得有效之能量；在實體電路方面，本文已完成 100W 充電系統之雛形。因採用數位訊號控制器為核心，電路元件可簡化，且可經由程式控制能跟隨日夜間天氣情況及氣候變化來變動其電路工作狀態，因此充電系統可優於一般類比電路有著較靈活之控制方式。[[abstract]]This thesis aims to develop a digital signal processor to control a solar cell and wind turbine hybrid charging system, using solar cells, a wind turbine, and a lead acid battery in order to construct a buck-boost converter. The solar cells and wind turbine serve as the system’s main power sources, and the battery to stores energy. The output power of solar cells and wind turbine have large fluctuations according to changes in weather and climate conditions, unstable power may be adjusted to the most suitable output, with a buck-boost converter. This study designed a booster using a dsPIC30F4011 digital signal controller as its core, which is controlled by the perturbation and observation methods in order to obtain an effective energy circuit, with a complete 100W charging system. Using a digital signal controller as a core, and relatively simple circuit components, this generator can be easily controlled and charged, day and night, by a simple program that reads weather conditions and makes changes to the state of the system’s circuits through a flexible application
