Abstract
The described examples may relate to a method of operating an on-board power supply of an electrically drivable motor vehicle, in which at least one electrical machine is supplied with electrical energy from a vehicle battery connected to the on-board power supply via an inverter connected to the on-board power supply in an intended drive operation, and the inverter may include a radio interference suppression filter to reduce grid-bound interferences. In an example, at least the inverter may be electrically disconnected from the on-board power supply in a charging operation.
