Reducing Switch Count in a Self-Balancing Nine-Level Switched Capacitor Inverter: A Modified Approach

Renewable energy sources are becoming more and more popular as a way to minimize environmental damage while meeting the world’s expanding demand for electricity. However, particular components like DC-AC converters, trans- former/inductor absence operation, front-end DC-DC converters with high gain capacity, and high voltage at a selected level are needed for small-scale PV solar independent AC loads and for grid applications as well as. This study offers a step-up boost inverter with quadruple operation of 9-levels that solves the problem by using a switched capacitor approach with less complications. By utilizing the control scheme itself, the topology is intended to balance capacitor voltages without the requirement for sensors. A phase disposition- pulse width modulation (PD-PWM) control technique is employed in this topology. This work focuses on the switching operation modes of the anticipated inverter and presents experimentally confirmed simulation experiments carried out in MATLAB/Simulink. All things considered; this research presents a viable option for renewable energy systems that can assist in satisfying the demand for electricity while preserving the environment.
