1. A vehicle on-board electrical system, comprising:
an AC voltage charging connection;
a rechargeable traction battery;
a power factor correction filter, which directly connects the AC voltage charging connection to the rechargeable traction battery; and
a controller which is connected to the power factor correction filter in a driving manner;
wherein the controller switches the power factor correction filter from a single-phase operation to a three-phase operation when a terminal voltage at the rechargeable traction battery reaches a minimum three-phase voltage.
