A method is provided for operating a DC-DC converter (22) of a charger (20). The DC-DC converter has on a primary side a first transformation coil (28) and at least one second transformation coil (30) that are arranged in series one behind another and also alongside a secondary side transformation coil (48). A respective semiconductor switch is connected in parallel with the at least one second primary side transformation coil (30). The at least one second primary side transformation coil (30) is switched either on or off by the semiconductor switch depending on a present value of at least one operating parameter of the charger (20).
