Modified PDPWM control with MPPT algorithm for equal power sharing in cascaded multilevel inverter for standalone PV system under partial shading

<span lang="EN-US">In this paper, a modified particle swarm optimization (MPSO) based maximum power point tracking (MPPT) controller is used to track the of PV system using DC-DC boost converter technology. </span><span lang="EN-GB">To raise module's input DC voltage, was employed. The powered DC-AC multilevel PWM inverter, which then delivered output AC voltage solitary inductive load. Cascaded inverters are often condition in renewable energy applications because they easy use and have few parts. Ripples link capacitors cause low order harmonics inter inverter's voltage. Phase disposition pulse width modulation (PDPWM) has fewest harmonics. inverter cells' delivery not equal manner. In present strategy for improving sharing PDPWM photovoltaic proposed. on 9-level where each cell connected array running at MPPT under partial shadowing single phase inverters. MATLAB/SIMULINK software do simulations, findings demonstrate that method presented effective balancing way shared between different cells reducing ripple capacitor.</span>
