ABSTRACT:
The N converters of a UFC bridge system interconnecting an N-phase voltage source to N output loads, comprise each N bilateral switches connected to one end of the associated output load and (N-1) bilateral switches connected to the other end thereof. The (N-1) bilateral switches of the respective converters build up a polygonal assembly between the output loads which is selectively connected to the respective phases of the voltage source by selective control of the N groups of N switches and of the (N-1) groups of switches.
