Abstract
Maximum power point tracking is one of the crucial element in photovoltaic (PV) power systems. Most of the conventional maximum power point tracking (MPPT) systems utilize pulse width modulated (PWM) dc-dc converter. PWM dc-dc converters usually have higher switching loss and high electromagnetic interference. On the other hand, resonant converters show good efficiency, soft switching capabilities and capable of high frequency operation over the conventional PWM converters. This paper proposes an incremental conductance MPPT using LLC resonant converter for PV power systems. The converter and the MPPT algorithm are implemented using MATLAB Simulink environment. The simulation results show the good performance of LLC resonant converter for maximum power tracking under varying environmental conditions.
