MATLAB SIMULATION OF PV BASED ASYMMETRIC MULTILEVEL INVERTER

This paper deals with simulation of PV based seven level asymmetric multilevel inverter with boost converter using maximum power point tracking algorithm. Maximum power point tracking (MPPT) techniques are used in photovoltaic (PV) systems to maximize the PV array output power by tracking continuously the maximum power point (MPP).In this paper perturb and observe (P&O) is employed. The carrier based PWM is employed for the proposed multilevel Inverter. A detailed study of proposed PV based inverter is carried out in MATLAB /SIMULINK and the results are verified. Index terms: THD, PWM, maximum power point tracking (MPPT), perturb and observe (P&O), photovol taic (PV).
