Systems, apparatus and methods for electric vehicle charging via a power conversion system

A method comprising:

• receiving, in a controller of an electric vehicle (EV) charging system, first status information of at least one EV coupled to the EV charging system, wherein the EV charging system comprises:
• a plurality of first converters to receive grid power from a distribution network;
• a high frequency transformer coupled to the plurality of first converters;
• and
• a plurality of unidirectional rectifiers coupled to the high frequency transformer;
• based on a charge level of the first status information, controlling the EV charging system to provide a charging current to the at least one EV;
• receiving, in the controller, second status information of the at least one EV;
• and
• based on a charge level of the second status information, controlling the EV charging system to provide a charging voltage to the at least one EV.

An electric vehicle (EV) charging system comprising:

• a grid-tie module to directly couple to a distribution grid network at a grid connection and convert a grid voltage to a plurality of first high frequency AC voltages;
• a single high frequency transformer having a plurality of primary windings coupled to the grid-tie module to receive the plurality of first high frequency AC voltages and a plurality of secondary windings to output a plurality of second high frequency AC voltages;
• and
• a plurality of unidirectional rectifiers, each coupled to one of the plurality of secondary windings to receive one of the plurality of second high frequency AC voltages and provide a DC voltage to at least one EV charging dispenser.
