Environmental concerns have renewed the interest in electric vehicles. To gain
widespread use, electric vehicles will also have to offer good performance and be
reasonably priced. AC drive systems using modern semiconductors can provide
efficient operation at the required power levels, but their cost at present is still too
high. This paper discusses the development of an AC induction motor drive system
which potentially lowers cost by using a digital controller. The controller is shown to
implement a high performance field-oriented control, while keeping a low parts count
by maximizing use of interface circuits which are integrated onto the microprocessor
chip. Cost is further reduced by designing the system to reuse motor control
components for battery charging and eliminate the need for external circuits.
Experimental results are presented for a low power prototype system. / Graduation date: 1994
