An a-c electric drive system was installed and operated in a fully tracked, 12-ton military personnel carrier. The system consists of a conventional design 400 Hz brushless alternator, 2 d-c-link inverters using high power SCR's, 2 a-c induction motors, and the associated control circuitry.This paper presents the design criteria which must be met for a tracked vehicle and points out those areas which are unique in such a vehicle. Test results from over 600 miles of test track operation are presented.
