| dc.description.abstract | Photovoltaic (PV) is an important application of solar energy that widely used in microgrid systems. This thesis proposes a fast and accurate Maximum Power Point Tracking (MPPT) algorithm used for PV application where a dp/dv tracker and a second-order switching surface control technique are applied to perform fast switching in a boost-type converter. A fast action of tracking Maximum Power Point (MPP) and stable operation at the point are achieved as soon as the environmental conditions are changed. The operating principles of the proposed control technique and mathematical derivations of the control law and steady state characteristics are presented. Simulation result shows that the proposed controller has a dramatic improvement in terms of dynamic response comparing with conventional PI based MPPT controller. A 280 W prototype for the proposed controller is built and tested with PV panels. Experiment results show a good agreement with the derived theory. | en_US |
