Claim 7:
8. An on-board charger (OBC), comprising:
a power factor corrector (PFC) comprising a three phase active front end (AFE) connected to an AC electrical grid; and
a DC/DC converter receiving a regulated DC voltage from the PFC and configured to charge a high voltage battery;
a switch arranged between the AFE and the AC electrical grid that is able to interrupt current flowing between two phase arms of the three phase AFE;
wherein the power value is equal to a rated reference maximum power extracted from a three phase electrical grid, PMAX3∅, when the AC grid is a three phase electrical grid by actuating the switch in an open state in response to the PFC connected to the three phase electrical grid so that the switch interrupts current flowing between the two phase arms of the three phase AFE; and
wherein the power value is equal to a reference ⅔ PMAX3∅ when the AC grid is a single phase and a two phase or a split-phase electrical grid so that the switch allows current to flow between the two phase arms of the three phase AFE, wherein a third phase arm of the three phase AFE withstands a maximum value of the line current IMAX and the two phase arms of the AFE withstand a value of the line current equal to ½ IMAX.
