碩士 === 國立臺灣大學 === 機械工程學系 === 85 === The main purpose of this research is to explore the design of the integral-type solar collectors using a PV-powered water pump , including the controller design of the circulation pump and the solar panel. First of all , we developed and built the test technology of the system components, including the test of the solar panel characteristics , the determination of the brushless D.C. motor parameters and the test of the system circulation flow resistance , etc. Additionally , we also developed a simulation model to predict the performances of the solar collector system. In order to improve the performances of the solar collector system , in this research , we designed two controllers , including power-regulating controller , for the purpose of motor protection；and maximun power point tracker（MPPT for abbreviation）. It has been shown by experimental resultsthat these controllers can improve system stability and reliability indeed.
