In this current research, the authors suggest employing intelligent controllers to create a buck-boost converter with zero-switching. The converter uses a network of independent buck-boost converters operating at different levels. Inductors play a critical part in the bridge circuit arrangement of converters, which is crucial for maintaining lossless switching circumstances such as zero voltage switching intermissions. These inductors, in conjunction with the turns ratio, augment the buck-boost converters' high-voltage gain and conductivity. The output voltage and current from a multilevel inverter have lower harmonic losses than those from a single-conversion system with the same characteristics. This converter features an intelligent controller, such as a Fuzzy controller, which boosts the voltage and current at the optimal switching times. A simple and more dependable controller, the fuzzy logic controller achieves a quick transient response, reduced overshoots, and will decrease voltage and current harmonics. The traditional controller's converter efficiency is enhanced by the fuzzy logic controller's precise voltage regulation. All aspects of the converter, from implementation to design, are done in MATLAB/Simulink, taking into account the various switching requirements of actual operation.
