Advances in Natural and Applied Sciences Simulation and Implementation of Active Neutral Point Clamped Multilevel Inverter Powered by Pv Source

In recent years, there has been an increasing interest in electrical power generation from renewable-energy sources such as photovoltaic systems. Due to the increased use of renewable energy and power electronic applications, various topologies of multilevel inverters are developed. This paper presents a three-level active neutral point clamped multilevel inverter powered by photovoltaic panel. A multicarrier phase disposition pulse width modulation is investigated for the proposed multilevel inverter to improve the spectral quality of the output voltage. MATLAB/SIMULINK is used for the implementation of the circuit model and the results are presented. Spartan FPGA is employed for the generation of gating pulses. A prototype of the proposed three-phase ANPCMLI is developed by employing IGBTs and it is powered by photovoltaic panel. The simulation results are verified experimentally.
