This paper presents a three-level ANPC AC/DC converter designed as an input stage on the grid side for an EV fast-charging system with a bipolar +/- 750 V DC-link. A 20 kVA prototype is shown based on a universal All-SiC MOSFET ANPC submodule for each phase leg. The focus is put on the design of the experimental model, along with the description of the control of the system, and its validation both in simulation and in preliminary experimental tests, with switching frequency at 62.5 kHz. The study shows that such a converter can be competitively employed as an input stage on the grid side for an EV fast-charging system using modularized power modules.
