A power converter system 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 and a plurality of
transformers. The system further comprises a plurality of dc link
capacitors, each coupled across a corresponding bridge. The system also
includes a controller 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.
