Abstract
Twelve-pulse rectifiers include a first controller that controls a first six-pulse rectifier, a second controller that controls a second six-pulse rectifier and a data network that couples the first controller and the second controller to exchange data therebetween. The first and second controllers preferably have a common architecture and preferably operate independently. Each controller preferably controls its associated six-pulse rectifier as a function of the current and/or voltage output of the associated six-pulse rectifier, preferably using conventional feedback control techniques. Moreover, the first controller also preferably controls the first six-pulse rectifier as a function of a second current at the second six-pulse rectifier output, and the second controller preferably controls the second six-pulse rectifier as a function of a first current at the first six-pulse rectifier output. Thus, each six-pulse rectifier may be controlled as a function of the current at the other six-pulse rectifier output. The first controller preferably receives second data representing the second current at the second six-pulse rectifier output via the data network, and the second controlle…
