A direct current (DC) fast charger for charging batteries of electric vehicles (EVs) that includes a primary circuit, with seven bidirectional switches, electrically linked to a primary wire of a transformer and configured to receive alternating current (AC) voltage; and a secondary circuit, including a plurality of diodes arranged to rectify AC voltage into DC voltage, that is electrically linked to a secondary wire of the transformer, such that the DC fast charger unidirectionally converts AC voltage received at the primary circuit into DC voltage output by the secondary circuit.
