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 16):
The network feedback unit as claimed in  claim 15 , wherein\n the first buck converter and the second buck converter each have at least one semiconductor switching device, and the controller unit further comprises: a first PWM generation unit, wherein the first PWM generation unit generates a first pulse-width-modulated drive signal for the at least one semiconductor switching device of the first buck converter depending on the first current setting signal; a second PWM generation unit, wherein the second PWM generation unit generates a second pulse-width-modulated drive signal for the at least one semiconductor switching device of the second buck converter depending on the second current setting signal; and a current sensor, which measures the filter capacitor current, wherein the balancing signal generation unit comprises: a comparator, which is operatively connected to the current sensor, which comparator outputs a comparator signal having a first logic state when the filter capacitor current is greater than an upper threshold value and outputs the comparator signal having a second logic state when the filter capacitor current is lower than a lower threshold value; and a logic unit having at least one logic gate, at least one integrating element and/or at least one sampling element, wherein the logic unit is supplied with the comparator signal and the pulse-width-modulated drive signals and generates the balancing signal depending on the comparator signal and the pulse-width-modulated drive signals.
