PERFORMANCE ANALYSIS OF A REGENERATIVE BRAKING SYSTEM WITH AN INDUCTION MOTOR-DRIVEN SUPERCAPACITOR THROUGH MATLAB SIMULINK SIMULATION

Abstract

This study analyzes the performance of a regenerative braking system that integrates a supercapacitor with an induction motor. The method used was quantitative with an experimental approach through MATLAB Simulink simulation as an analysis tool. The system’s behavior is observed during both acceleration and deceleration phases. Results indicate that no energy recovery occurs during acceleration. However, during deceleration, significant fluctuations in current, voltage, and battery State of Charge (SOC) signal that energy is being recovered. When regenerative braking is applied, the SOC drops only 1% over 2.5 seconds, compared to a 3% drop without it, illustrating improved battery efficiency. The integration of a supercapacitor proves effective in absorbing current and voltage spikes, thereby reducing stress on the battery and enhancing its longevity. Nevertheless, the addition of the supercapacitor does not lead to a substantial improvement in overall energy recovery efficiency; in fact, a slight decrease is noted. These findings reveal the trade-offs involved in supercapacitor integration and serve as a valuable reference for optimizing future regenerative braking systems.
