Abstract
A motor generator set is used to convert 60-Hz line voltage to 400-Hz voltage for use in the high-power transmitter. The motors used in the motor generator sets are either 1750- or 3500-hp synchronous motors. They must be brought up to speed before line voltage can be applied to avoid severe power-line transients. The present unit being used to bring the motor up to speed is an open-loop analog device and cannot compensate for drift, temperature changes, or line frequency changes. The design of the new unit will compensate for all variations and is simple to set up and maintain.
