Abstract

PURPOSE: To prevent the interruption of DC current, by compulsively causing commutation failure to other remaining groups, if one group is at commutation failure in inverting units.
CONSTITUTION: If the inverter 14 is at commutation failure, the commutation failure detection circuit 52 detects the failure and produdes a signal to the phase control circuit 51 of the group B. The phase control circuit 51 receiving the signal from the commutation failure detection circuit 52 gives the trigger pulse so that the inverter 24 is at DC short circuit to the inverter 24 of the group B, that is, the same phenomenon as the commutation failure of the inverter 14 of the group A is caused. Thus, the DC current of the group B is increased as for the group A to avoid the interruption of the DC current. If the group B is in failure, the inverter 14 of the group A is in DC short circuit to prevent the inerruption of DC current.
