Analysis of Kinetic Energy Recovery System Based on Four-Phase Interleaved Buck Converter for Vehicle Verification Processes

The automotive industry consumes large amounts of fossil fuels during vehicle acceleration and braking tests as part of quality verification. The kinetic energy generated in the test rollers is typically wasted during vehicle braking. One approach to reducing vehicle production costs and improving the efficiency of fossil fuel consumption is to recover a fraction of this energy using a system that does not interfere with vehicle verification standards. The recovered energy can be stored or used for other essential functions, such as powering lighting systems. In industrial processes, electrical energy is the most common form of energy recovery due to its advantages in storage, distribution, and transformation for various applications. This paper presents the analysis of a kinetic energy recovery system (KERS) based on a four-phase interleaved Buck converter for vehicle testing processes. A stage by stage analysis of the energy recovery system is provided, along with the selection of system parameters. Furthermore, the advantages of the proposed topology and the experimental results are discussed.
