“…In [8] a cascaded H-bridge converter is employed to interface the medium voltage grid, while a dual active bridge converter with galvanic isolation serves as a wide output interface with EVs. Another wide output solution, based on a reconfigurable LLC resonant DC-DC converter, is presented in [9]. On the other hand, there are solutions without galvanic isolation; for instance, in [10], [11], [12], topologies based on the partial power converter concept have been proposed.…”

This paper proposes a new buck-boost flyingcapacitor (FC) converter for the DC-DC stage of an Electric Vehicle (EV) fast charging station. The proposed converter is capable of delivering a wide output range of voltage to charge different battery configurations. The converter has two modes of operation, buck and boost. Thanks to this feature, the proposed converter allows higher efficiency and a wide operating range. The proposed converter is capable of supplying a voltage range from 200 V to 1000 V at its output, which shows the feasibility of occupying the converter inside a charging station that allows charging 400 V and 800 V battery systems. The average efficiency reported is over 97%. It is concluded that the proposed buckboost FC converter is suitable for modern wide-output EV fast charging applications.
