An on-board charger (OBC) for charging a traction battery of an electric vehicle includes a primary phase, a secondary phase, and a pre-charge circuit. Each phase includes a circuit having an input and an output. The primary phase circuit input is connectable to a mains supply to connect the primary phase to the mains supply. The secondary phase circuit input has an input capacitor. The pre-charge circuit is connected between the circuit outputs and is switchable between an open state in which the pre-charge circuit disconnects the circuit outputs and a closed state in which the pre-charge circuit connects the circuit outputs. When the pre-charge circuit is in a closed state, current may flow from the primary phase circuit output, through the pre-charge circuit, to the secondary phase circuit output, and through the secondary phase circuit to the input capacitor to charge the input capacitor.)
