Design of Maximum Power Point Tracker (MPPT) and PhaseLocked Loop (PLL) in a PV-Inverter

摘要

This paper deals with the design of the Maximum Power Point Tracker (MPPT) and Phase Locked Loop (PLL) controllers in a PV-Inverter. The methods to optimizing the load of the PV module in order to capture the highest amount of energy, despite that the solar irradiation and cell temperature never is constant. Four types of Maximum Power Point Trackers (MPPT) have been discussed and a novel MPPT algorithm has been developed. The tracking of the fundamental grid voltage, by means of a Phase Locked Loop (PLL) was discussed. All the controllers have been designed by standard design techniques, and verified by simulation in MATLAB? / SIMULINK? and PSIM
