Inventor: SAKAI TAKAMI
IPC: H02M5/45
Filed: 1978-09-08
Abstract: PURPOSE: To prevent DC short circuit and surely stop the operation of a converter, by detecting a bypass pair status to close a bypass switch on condition that the commutation of the converter failed.  
     CONSTITUTION: A plurality of convertes 10, each of which comprises Graetz-connected semiconductor rectifiers U∼Z, are coupled in cascade to one another and provided with bypass switches 11. When a stop signal is applied for a converter 10 1 , an AND circuit 20 gemerates an output "1" to apply a bypass pair instruction. When bypass pair operation is properly effected and commutation failure is detected, another AND circuit 21 generates an output "1" to apply a bypass switch closing instruction to turn on a bypass switch 11 1 . The bypass pair status is detected on condition that the commutation of the stopping converter has failed. Therefore, the converter can be surely stopped without DC short circuit by using a conventional commutation failure detector 17.
