Abstract:
A network feedback unit is designed to feed electrical energy from a voltage intermediate circuit into a three-phase network, wherein the network feedback unit has: a buck converter unit having a first buck converter and a second buck converter, wherein the first buck converter and the second buck converter are connected in parallel and the input side of each of which is electrically coupled to the voltage intermediate circuit, an inverter, the input side of which is electrically coupled to an output of the buck converter unit and the output side of which is electrically coupled to the three-phase network, at least one filter capacitor, which is arranged at the output of the buck converter unit or at the output of the inverter, and a controller unit, which is designed to drive the first buck converter and the second buck converter depending on a filter capacitor current in such a way that the first buck converter and the second buck converter contribute in equal parts to an output current of the buck converter unit.

Claim (Index 15):
The network feedback unit as claimed in  claim 11 , wherein the controller unit comprises:\n an intermediate circuit voltage controller, which regulates an intermediate circuit voltage to a setpoint value, wherein the intermediate circuit voltage controller outputs an output current setpoint value of the buck converter unit as a manipulated variable; a buck converter unit current controller, which depending on a difference between the output current setpoint value of the buck converter unit and the output current of the buck converter unit and depending on a balancing signal, generates a first current setting signal and generates a second current setting signal, wherein the first current setting signal influences an output current of the first buck converter and the second current setting signal influences an output current of the second buck converter; and a balancing signal generation unit, which generates the balancing signal depending on the filter capacitor current such that the balancing signal is dependent on the parts in which the first buck converter and the second buck converter contribute to the output current of the buck converter unit.
