Abstract
The present invention specifies a converter for an electrical machine. A power circuit breaker (T1) comprises at least two semiconductor elements (9, 10) connected to one another to form said power circuit breaker. At least one control circuit (C1, C2, 14) is associated with the at least one power circuit breaker (T1) and is connected to a respective control input of each of the at least two semiconductor components (9, 10) in order to selectively switch the same on and off by means of respective switching signals (S1, S2). The switching signals (S1, S2) are generated on the basis of switching losses and conduction losses of the power circuit breaker (T1).
