Abstract
A description is given of an advanced ac drive system for use in electric vehicles. In this project the system comprises an induction motor, a PWM transistorized inverter, a variable ratio gear box and a controller. Special features of the drive system are described, with the emphasis on the control strategy used to optimize performance. Experimental results show that the control strategy is highly satisfactory and the controller is reliable, robust and low cost. Also the battery prediction device developed in the project gave reliable information on the state-of-charge of the battery pack and the residual range of the EV, which will certainly increase the driver's confidence in EV.
