Method for operating a frequency converter and frequency converter operating by the method

摘要

The method involves controlling semiconductor switches by a control logic (34) based on generated control signals (32), where the control logic obtains data for voltage-impressing modulation and data for current-impressing modulation. A logic UND-conjunction of the obtained data is carried out by the control logic for generation of the control signals. The data for voltage-impressing modulation are generated based on a voltage reference value (40) that is supplied to a signal generator (36). Independent claims are also included for the following: (1) a power converter device comprising a power converter (2) a computer program comprising instructions to perform a method for operating a power converter (3) a storage medium comprising instructions to perform a method for operating a power converter.
