CURRENT SOURCE INVERTER WITH UNINTERRUPTED SWITCHING BETWEEN CLOCKED VOLTAGE REGULATED OPERATION AND FUNDAMENTAL FREQUENCY UNREGULATED OPERATION AND METHOD FOR UNINTERRUPTED SWITCHING OF SUCH AN INVERTER

摘要

A current source inverter is disclosed, comprising: means for operating the inverter in fundamental frequency unregulated operation, means for operating the inverter in clocked voltage regulated operation, means for recording parameters from which conclusions can be drawn at an instantaneous operating point and/or at an instantaneous network condition, means for determining an appropriate operating condition from the recorded parameters and means for uninterrupted switching of the operation of the inverter to the operating condition as determined from the recorded parameters and a method for uninterrupted switching of such a current source inverter.
