An advanced alternating current electric drive system is being developed by the General Electric Company for Ford Motor Company's ''Advanced Electric Vehicle Powertrain Effort,'' which is a major element of DOE's Single Shaft Electric Propulsion System Program. The integrated transaxle consists of an oil-cooled 50 hp ac induction motor mounted within a 2-speed transaxle. Direct current from the nominal 204 V battery pack is converted to variable frequency, variable voltage 3-phase ac current by a liquid-cooled transistor inverter. A custom-designed inverter motor controller, containing two 8751 microcomputers plus analog and digital circuitry, translates torque commands from the controller to the inverter transistor base drivers that turn on/off power Darlington transistors at appropriate times. After a review of the electric drive system ratings, details of the transistor inverter are presented. Control strategy and controller design are summarized. Electric drive integration and system test results are given.
