Converter assembly and method for operating a converter assembly

Converter assembly comprising at least two converters and a control unit connected to the at least two converters,

• wherein the control unit is designed, continuously or at discrete time intervals,
• to transmit electrical power to the at least two converters, wherein the electrical power is within an electrical power range, of a minimum power value Pmin and a maximum power value Pmax,
• to determine the current electrical power balance of each of the at least two converters or to receive the electrical power balance from same, and
• to calculate the electrical power balance of the converter assembly,
• to adjust the electrical power range of each of the at least two converters,
• wherein the at least two converters are supplied by an intermediate circuit with voltage, VDC,
• the electrical power range adjusted if VDC falls below a predetermined value or exceeds a predetermined value, and
• to adjust the electrical power range of the at least two converters in such a way that the power balance of the converter assembly is within a predetermined range.
