Solar Integrated Cascaded Topology of Multilevel Inverter Using Interval Type-2 Fuzzy Logic Controller.

With the evolution of an advanced power system concept, green power supplies, comprising transmission and distribution designed networks, were progressively implemented in this research. Consequently, optimum usage of cascaded H-bridge inverter topologies and power distribution activities is crucial for long-term production. Selective harmonics elimination techniques have always been required to attain the appropriate switching frequencies of multilevel inverters. This study aims to estimate the switching frequency for solar-integrated multilevel inverters utilizing boost converters to decrease the total harmonic contents utilized in grid applications. This study contributes to the optimum feasible solution by utilizing a number of recently discovered dynamic controller methods: Type I Fuzzy controller and Interval Type II Fuzzy controller. Seven-level, eleven-level, and fifteen-level MLIs minimize overall harmonic components. The dependability and convergent rates of simulation results with different modulation indices are produced and compared for seven-, eleven-, and fifteen-level MLIs. In addition, as compared to existing control systems, the suggested controller reduces Total Harmonic Distortion and delivers stabilized output power. The suggested IT2-FLC is compared against an T1-FLC and a standard mathematical PI controller. [ABSTRACT FROM AUTHOR]
