Abstract
In a system and method for operating a system having a rectifier which is suppliable from an electric AC-voltage supply network, an inverter which feeds an electric motor, and a DC/DC converter which is connected to an energy accumulator, the DC-voltage side connection of the inverter is connected to the DC-voltage side connection of the rectifier, in particular, the electric motor is supplied from the AC-voltage side connection of the inverter, a first DC-voltage side connection of the DC/DC converter is connected to the DC-voltage side connection of the rectifier, in particular, the DC-voltage side connection of the inverter and the first DC-voltage side connection of the DC/DC converter are connected in parallel, the DC/DC converter has a housing in which a device for current acquisition is situated, which acquires either the current, in particular network phase currents, flowing into the rectifier at the AC-voltage side connection of the rectifier, or the current emerging from the rectifier at the DC-voltage side connection of the rectifier, and the acquired value is forwarded to a signal electronics situated in the housing of the DC/DC converter, which generates control signal…
