METHOD FOR OPERATING AN ELECTRIC INDUCTION OR TRAVELLING WAVE MACHINE

摘要

The invention relates to a method for operating an electric induction or travelling wave machine (10) by means of a converter (40) having a plurality of half bridges (71, 72, 73, 74, 75, 76), wherein associated with each half bridge (71, 72, 73, 74, 75, 76) is a winding (11, 12, 13, 14, 15, 16) of the induction or travelling wave machine (10) and a transfer unit (23, 24, 25, 26, 27, 28) connecting the half bridge (71, 72, 73, 74, 75, 76) to the winding (11, 12, 13, 14, 15, 16), wherein a defect on a half bridge (71, 72, 73, 74, 75, 76) or on a winding (11, 12, 13, 14, 15, 16) of the induction or travelling wave machine (10) or on a transfer unit (23, 24, 25, 26, 27, 28) is detected. A half bridge (71, 72, 73, 74, 75, 76) that must be operated in a limited manner or shut down in order to be able to continue to operate the electric induction or travelling wave machine (10) is determined. The determined half bridge (71, 72, 73, 74, 75, 76) continues to be operated in a limited manner, or is shut down.
