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