The braking energy in diesel-electric locomotives is typically wasted into resistors. A more energy-efficient way is to store and recycle such energy. Thus, this article proposes a multiport power conversion system as the core of a hybrid energy storage system, based on Lithium-ion (Li-ion) batteries and supercapacitors (SCs). In such configuration, SCs
