An electric drive for driving at least one power converter and/or electric motor, having a mains supply connection for providing electric power to the electric drive, a redundant feeding system comprising at least two feeding units, namely a first non-regenerative front end or active front end and a second non-regenerative front end or active front end, power electronics components for connecting the mains supply connection to the feeding system, a control system for controlling the feeding system, and a DC-link connection for connecting the electric drive to a DC-link. The disclosure further discloses a method for operating a corresponding electric drive.
An electric power converter for providing electric power to at least one electric device, such as an electric motor, comprising a mains supply connection for providing electric power to the power converter, a redundant feeding system comprising at least two feeding units, namely a first non-regenerative front end (NFE) or active front end (NFE) and a second non-regenerative front end (NFE) or active front end (NFE), power electronics components for connecting the mains supply connection to the feeding system, a control system for controlling the feeding system, and a DC-link connection for connecting the power converter to a DC-link, wherein the control system is provided to limit an over-current and/or overload passing through the feeding system by creating a trip signal for disconnecting the feeding system at least partially from the power electronic components of the power converter.
