Medium scale prototype of a regenerative braking system and voltage stabilizer

Abstract

This paper presents a medium scale prototype of a system to store the excess energy present in a DC electrical system, based on Ultra-capacitors and driven by a DC-to-DC converter. The prototype is first intended for research and pedagogic proposes, and second as a voltage stabilization system in Medellin's Metropolitan Train System where it is being implemented. This allows students and researchers to perform experiments regarding regenerative braking, power line compensation and high-current DC-DC electronics. It is based in previous work with simulations and a small prototype developed for the student in the Electrical and Electronics Laboratory in the Universidad Pontificia Bolivariana.

Overcoming voltage fluctuation in electric vehicles by considering Al electrolytic capacitor-based voltage stabilizer

“…Some researchers have conducted indepth studies on the characteristics of voltage stabilizers and their applications in various electrical and electronic systems. Some examples of voltage stabilizer research such as research on optimizing inductor-capacitor circuits (Kawashima et al, 2009), application of voltage stabilizers on modern materials (Englund et al, 2009), voltage doubler simulation using MATLAB (Balamurugan et al, 2014), ultra-capacitor-based voltage stabilizer (Villegas et al, 2015), automatic voltage regulator with an angle-based switching strategy (Batmani and Golpîra, 2019), capacitors design for voltage stabilizer (Farsadi et al, 2016), and Pareto analysis (Torreglosa et al, 2016) have contributed to improving the performance quality of the voltage stabilizer.…”
