1. A method comprising:
receiving, in a controller of an electric vehicle (EV) charging system, an indication of connection of at least one EV to a dispenser coupled to the EV charging system, wherein the EV charging system comprises:
a plurality of first converters directly coupled to receive grid power from a distribution network, the grid power at a medium voltage AC voltage;
a single high frequency transformer coupled to the plurality of first converters; and
a plurality of unidirectional rectifiers coupled to the single high frequency transformer;
determining a charging level to be supplied to the at least one EV; and
based at least in part on the charging level, controlling one or more of the plurality of first converters to supply the charging level to the at least one EV.
