Reduced Device Count for Self Balancing Switched-Capacitor Multilevel Inverter Integration with Renewable Energy Source

In this study, a new switched-capacitor-based seven-level inverter topology with photovoltaic system is presented. The proposed requires smaller number of devices and has the ability to self-balance voltage across capacitor. configuration simple extend higher levels voltage. This multilevel suitable for low- medium-voltage applications (PV) integration. To improve PV efficiency as an input DC–DC boost converter, Fuzzy logic-based maximum power point controller technique used. A converter integrates topology. anti-predatory particle swarm optimization (APSO) used solve non-linear transduction equations (7L−PV−SCMLI) APSO described minimize harmonics in (MLIs), which complex problem involving transcendental equation. Furthermore, can be applied order all symmetrical asymmetrical MLIs that have equal non-equal DC sources. APSO-based selected harmonic elimination (SHE) obtained best switching angle value, optimized angles reduced total distortion (THD) 7L−PV−SCMLI.
