Abstract
In this paper, a DC-DC converter with an innovative topology for automotive applications is proposed. The goal of the presented power converter is the electrical storage system management of an electric vehicle (EV). The presented converter is specifically compliant with a 400 V battery, which represents the high-voltage primary source of the system. This topology is also able to act as a bidirectional power converter, so that in this case, the output section is an active stage, which is able to provide power as, for example, in the case of a low-voltage battery or a supercapacitor. The proposed topology can behave either in step-down or in step-up mode, presenting in both cases a high gain between the input and output voltage. Simulation results concerning the proposed converter, demonstrating the early feasibility of the system, were obtained in a PowerSIM environment and are described in this paper.

Summary
The idea of a sustainable society represents a goal for all the major drivers of technological progress in several fields. Mobility plays a key role in this, since it has long been a primary need of human beings; it has stimulated notable interest from industries and researchers as far as the use of sustainable energy sources is concerned. The idea of eco-sustainable mobility is increasingly strong; in particular, there is an increasing focus on electric mobility. To be truly ecologically sustainable, electric mobility must use energy arising from renewable sources. In order to use power at any time, storage systems are fundamental to compensate the typically intermittent nature of the power generated by means of renewable sources. In the general scenario of sustainable electric mobility, made of renewable sources, electric storage systems and electrical drives, power electronics assumes a fundamental role, consisting in the interconnection between all these components in order to produce smart and efficient energy conversion
