11. Method for operating a converter assembly with at least two converters and a control unit connected to each of the at least two converters, comprising the following steps:
a. transmitting, via the control unit (1), electrical power to each of the at least two converters, in a range with a minimum power value Pmin and a maximum power value Pmax,
b. receiving or calculating, via the control unit, the current power balance of the each of the at least two converters,
c. calculating, via the control unit, the power balance of the converter assembly,
d. adapting, via the control unit, the electrical power range of the at least two converters if the voltage VDC of a DC voltage intermediate circuit supplying each of the at least two converters falls below a predetermined value or exceeds a predetermined value, and
e. adapting, via the control unit, 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.
