Description
Summary:Research on FPGA controlled three phase Photovoltaic (PV) inverter using Multi-Carrier Pulse Width Modulation (MC-PWM) is presented in this article. In this proposed work, reduced active switching count, transformers, Single DC input (SDC), modular topologies and redundancy are key advantages. The proposed three-phase five level Multilevel Inverter (MLI) with SDC source using three-phase transformer is controlled by MC-PWM schemes. To evaluate the performance of the inverter, a Phase Disposition (PD), Phase Opposite Disposition (POD) and Alternate Phase Opposite Disposition (APOD) have been proposed. The effectiveness of the inverter is analyzed in terms of Total Harmonic Distortion (THD) by varying the Modulation Index(MI). Field Programmable Gate Array (FPGA) can realized for generation gating pulses to the inverter. The results were analyzed through MATLAB/Simulink and validated by FPGA based experimental setup.
