  • SEMI-DIRECT VARIABLE SPEED DRIVE WITH N+1 POWER AVAILABILITY
    Publication number: 20100225165
    Abstract: A system for controlling a speed of each of N variable speed motors with a drive voltage is disclosed, where N is an integer equal to or greater than 1. The system includes (N+1) generators and a switching arrangement configured to directly couple, in a one-to-one relation, the N variable speed motors to the (N+1) generators so that any one of the N variable speed motors is capable of operating in at least a first mode and a second mode. In the first mode the any one of the N variable speed motors is driven with the drive voltage generated by a first generator of at least two of the (N+1) generators, and in the second mode the any one of the N variable speed motors is driven with the drive voltage generated by a second generator of the at least two of the (N+1) generators.
