碩士 === 國立中正大學 === 電機工程研究所 === 101 === This thesis presents a maximum power point trackers (MPPT) for dc-microgrid. The proposed MPPT topology consists of a buck and a boost converter to accommodate wide output voltage range of PV panels. T-S fuzzy algorithm is employed to track the maximum power point of the PV panels to increase the transfer efficiency. In addition, we compared perturbation and observation algorithm with T-S fuzzy control. Finally, experimental results of the MPPT with T-S fuzzy control have verified that the maximum power tracking accuracy can reach 99%. Maximum power tracking speed and response to the changes in the atmosphere are better than perturbation and observation algorithm. The experimental results prove that T-S fuzzy method can indeed achieve maximum power tracking.
