Pi And Fuzzy Logic Controlled Multiple Lift-Push-Pull Switched Capacitor Luo Converter

Abstract

This study shows a simulation using PI and fuzzy logic controllers for a newly constructed elementary P/O push-pull switched capacitor Luo converter circuit. This incorporates both voltage lift and switched-capacitor technology. Power electronic converters' dynamic behavior becomes quite non-linear due to their time-varying and switching nature. Fuzzy logic controllers can be utilized as feedforward controllers for power electronic converters because conventional controllers are unable to provide high dynamic performance. By taking repeated measurements of the converter output voltage at specific points during a conduction period, the Control algorithm is created in this study to ensure tracking of the reference voltage and rejection of system disturbances. The main aim is a simulation of PI and Fuzzy logic controls using MATLAB/ Simulink software to evaluate the controller’s performances. The simulation results show Fuzzy controller performs effectively for the preferred converter.
