A Reduced Switch Count Multilevel Inverter based Hybrid Energy System

The article presents a comparative analysis of conventional cascaded H bridge inverter and reduced switch count MLDC link structure of multilevel inverter (MLI) with the least number of switches for a single-phase hybrid energy system. Cascaded H-bridge multilevel inverter (CHB-MLI) is more suitable for renewable energy applications. Renewable-energy sources (RES) including solar, fuel cell wind, etc possess intermittent nature which motivates the research toward hybrid energy systems. The presented hybrid energy system includes fuel cells and solar photovoltaic. A multi-carrier pulse width modulation (PWM) technique is used for generating a pulse for the hybrid energy-based inverter. Proposed system is simulated in MATLAB/Simulink environment.
