Abstract :
This work is focused on a photovoltaic system with a three-level neutral-point-clamped quasi-z-source inverter. The maximum power point tracking algorithms based on dP/dV feedback, perturb and observe and incremental conductance have been adapted and tested in this topology using the shoot-through duty cycle as control variable. Simulation results using SimPowerSystem from Matlab/Simulink are presented.
