PI controller for photovoltaic-fed novel multilevel inverter topologies

This research describes the analysis and design of a unique 7-level 9-level multi-level inverter topology with fewer DC power supplies switches, comparison using pulse width modulation (PWM). Comparisons inverters that analyze characteristics optimal nearest level (ONLM) technology are made various PWM approaches such as (NLM) technique, phase disposition (PD), opposition (POD), alternate (APOD). The output is evaluated based on high Vrms, low total harmonic distortion (THD) profile. controller artificial intelligence (AI) machine learning (ML) techniques. ONLM techniques used to measure voltage harmonics full load, several offset values used. control provided validated MATLAB/Simulink simulation tools laboratory-based experimental testing.
