On board charger for electric vehicles
First Claim
1. On board charger for electric vehicles, the on board charger having an AC input and a DC power output and comprising a housing that contains a power electronic circuit, a control electronic circuit, capacitors, inverters, at least one transformer, at least one input inductor and at least one output inductor inside to allow the conversion of input AC power into output DC power, the base of the housing incorporating a cooling circuit, the at least one transformer, the at least one input inductor and the at least one output inductor are arranged in a shared common volume in a compartment delimited by several side walls and the base of the housing of the on board charger and at least one internal wall, such that the compartment is at least partially filled with potting which at least partially covers the at least one transformer, the at least one input inductor and the at least one output inductor, these three elements constituting one magnetic block.
