A power converter system (12) for supplying an output voltage is provided. The power converter system is adapted to operate in a normal mode and a fault mode. The system comprises a plurality of bridges (14, ... 19, 90) and a plurality of transformers (20 ... 25). The system further comprises a plurality of dc link capacitors (32 ... 37), each coupled across a corresponding bridge. The system also includes a controller (11) adapted for, during the normal mode, switching each bridge with a respective normal phase shift. During the fault mode, the controller is adapted for switching each of the remaining ones of the bridges with a respective adjusted phase shift to generate the output voltage. During the fault mode, at least one of the plurality of bridges is bypassed.
