A direct current (DC) fast charger for charging batteries of electric vehicles (EVs) includes a primary circuit having nine switching groups, each switching group having a plurality of switches electrically connected in series, that are electrically linked to primary wires of a transformer and configured to directly couple to an electrical grid to receive three-phase alternating current (AC) power and increase the frequency of the AC power; and a secondary circuit, including six switches or diodes arranged to rectify AC power into DC power, that is electrically linked to a secondary wire of the transformer.
