This study examines the efficacy of a super-lift Luo converter for electric vehicle (EV) battery applications, aiming to determine an appropriate control strategy under fluctuating voltage situations. The converter is controlled by two methods: sliding mode control (SMC) utilizing pulse width modulation (PWM), and the traditional proportional-integral (PI) controller. A comprehensive comparative analysis is conducted in MATLAB/Simulink by modeling the converter using both continuous DC and lithium-ion battery voltage sources. The simulation findings indicate that an input of 12 V produces 36.07 V with SMC and 36.27 V with the battery source, while SMC attains an efficiency of 91.25 %. In comparison to the PI controller, SMC demonstrates a more rapid settling time and enhanced dynamic response in variable voltage settings. This simulation-based work offers significant insights into the selection of control algorithms for modern DC-DC converters utilized in electric vehicle systems. The findings demonstrate that SMC-controlled super-lift Luo converters provide a reliable and effective solution for electric vehicle battery systems.
