Solar Fed Nine Level Quadruple Boost Inverter with Fuzzy Controller

In recent years, AC high-voltage applications and renewable energy are driving the rising use of multi-level inverters (MLIs) with switching capacitors. Using the voltage across the capacitor, the switched capacitor (SC) method reduces the amount of DC sources needed to provide the desired yield voltage. It takes a lot of work to design a high-gain MLI that uses few sources and switches efficiently. In contrast to the previous SC-MLIs architecture, this work presents modelling of a 9-level (9-L) quadruple boost inverter (NQBI) structure that is supplied by a single photovoltaic system and uses less diodes, switches and capacitors. By skilfully balancing the outputs of the 2 capacitors, the suggested NQB converter generates an output with nine distinct voltage levels. The suggested 9-L QBI architecture is compared to the different SC-MLIs to show its advantages and disadvantages. The suggested grid-free QBI that uses solar photovoltaics has been thoroughly simulated in a MATLAB/SIMULINK environment under varying situations to confirm its effectiveness.
