The thesis reports an investigation into the operation and performance of a 12-pulse parallel bridge rectifier system supplied from a three winding-transformer and operating without an interbridge reactor. The work has been undertaken in liaison with GEC Transmission and Distribution Projects Ltd, Stafford. The conventional centre-tapped interbridge reactor on the dc side allows each bridge to operate independently of the other in its normal 6-pulse manner making the analysis fairly straightforward if the usual assumption of perfectly smooth direct current is made. The omission of the reactor can provide very substantial cost and space savings in high power installations. However, its absence leads to interaction between the bridge rectifiers, and this is of special interest here. [Continues.]
