Experimental Implementation of Cascaded H-Bridge Multilevel Inverter with an Improved Reliability for Solar PV Applications

This study presents the boost converter-based cascaded H-bridge (CHB) multilevel inverter with improved reliability for solar PV (photovoltaic) applications. The is associated converter to enhance DC link voltage by using maximum power point tracking-perturb and observe (MPPT-P & O) technique. proposed configuration aimed toward performance analysis of CHB MLI reducing number components, low total harmonic distortion (THD), reduced power, less cost function, standing (TSV), reliability, switching losses application. In this study, a used obtain stepped pure sinusoidal AC from array. extracts enhances higher which provides high efficiency. integrated 27-level generate near-sinusoidal output lower THD. tested linear nonlinear loads robustness, during dynamic loads, stable well suited grid-connected A detailed comparison presented on component count aspects existing MLIs MLIs. simulation outcomes implemented arrangement are help MATLAB/Simulink, an experimental prototype developed dSPACE RTI1104 controller also in research laboratory checking possibility arrangement.
