This study presents a three-level, interleaved, non-isolated DC/DC converter designed as a battery interface for an EV fast-charging system with a bipolar +/- 750 V DC-link. A 20 kW prototype is exhibited based on a universal All-SiC MOSFET submodule for each leg. The core of the paper is the design of the experimental model, along with the description of the system’s control, as well as validation in simulation and in introductory experiments. It is shown that such a converter employing modularized power modules can properly operate as the DC/DC interface.

Niniejsze studium przedstawia trójpoziomowy, dwugałęziowy, nieizolowany przekształtnik DC/DC, zaprojektowany jako interfejs akumulatora dla systemu szybkiego ładowania pojazdów elektrycznych z dwubiegunowym obwodem prądu stałego +/- 750 V DC. Zaprezentowano prototyp o mocy 20 kW w oparciu o uniwersalny submoduł (All-SiC MOSFET) dla każdej gałęzi. Istotą pracy jest zaprojektowany model eksperymentalny wraz z opisem systemu sterowania, a także walidacja w symulacjach i początkowych eksperymentach. W artykule przedstawiono, że przekształtnik wykorzystujący zmodularyzowane moduły mocy może prawidłowo pracować jako interfejs prądu stałego.
