Abstract
An energy converter includes a regenerative rectifier electrically connected to a DC voltage circuit and electrically connectable to a first AC voltage grid. The regenerative rectifier includes a first bridge arm with first and second power semiconductor modules connected in series and forming a first center-point pick-up connectable to a first AC voltage phase of the first AC voltage grid. The first power semiconductor module is electrically connected to a first DC voltage phase and the second power semiconductor module is electrically connected to a second DC voltage phase of the DC voltage circuit. First and second capacitors are connected in series and form a second center-point pick-up, with the first capacitor electrically connected to the first DC voltage phase and the second capacitor to the second DC voltage phase of the DC voltage circuit. A coil is electrically connected between the first center-point pick-up and the second center-point pick-up.
