A High Step-up Sextuple Voltage Boosting 13S-13L Inverter With Fewer Switch Count

Abstract

In this work, a high step-up sextuple voltage boosting 13 switches – 13 level inverter (SVB- 13S -13LI) structure was proposed through a pulse width modulation technique with selective harmonic elimination. This topology can deliver six times of voltage boosting capability. A single voltage source, 13 switches, two diodes, and three capacitors are utilized to obtain the objective of this research. This work carried out various tests on the proposed topology to find efficiency, voltage stress, total standing voltage, and voltage gain. The detailed comparative study of existing inverter topologies is tabulated to prove the proposed topology has a better performance. The main feature of this topology is six times voltage boosting, a minimum number of switches, less voltage stress, and a self-balanced floating capacitor. Further to isolate or eliminate the undesired low order harmonics the particle swarm optimization-based SHPWM Technique is used. For proving the above-mentioned merits, the simulation was carried out using MATLAB SIMULINK and their corresponding THD results are compared with different Modulation indexes. Also, experimental results are validated by the FPGA SPARTAN 6E controller and their cost function [CF] for the unit price ( $\$ $ ) are compared with the state-of-art literature 13-level inverters.
