A Single Phase Grid Connected Hybrid Multilevel Inverter for Interfacing Photo-voltaic System

This paper introduces a new single phase hybrid multilevel inverter with a minimum number of switches for a Photovoltaic application. A Perturb and observe maximum power point tracking is used for tracking maximum power from solar panel. A boost converter is used for boosting the generated voltage because proposed inverter operates at the asymmetric condition. The proposed inverter is the combination of reduced switch topology and cascaded H-Bridge topology. Two types of Phase Disposition carrier arrangement with sinusoidal reference is utilized for generating the gating pulses for proposed inverter. It generates a 15-level output voltage with 8.12% of total harmonic distortion.
