Abstract:
A converter system, comprising:a plurality of converters, at least one converter of the plurality of converters including power semiconductors which are switchable to an on state and an off state;at least one automation unit physically separated from the at least one converter and connected to the power semiconductors via at least one bus system, the at least one automation unit:adjusting a particular time at which the power semiconductors are switched into the on state and off state to influence a current flow through the power semiconductors, and controlling the particular time to control one of the desired overall voltage and the desired overall current at an output of the at least one converter; andintelligent interfaces, each of the intelligent interfaces being assigned to a corresponding one of the plurality of converters, each of the intelligent interfaces receiving the particular time and switching the power semiconductors into at least one of the on state and off state at the particular time, one of the at least one automation unit and the at least one converter sending a time standard for temporally synchronizing the intelligent interfaces with a precision of at least 10 .mu.s.
