Abstract :
The system performance of an AC variable speed drive directly depends on the current regulation. In this paper, a new space vector PWM scheme for current-regulated indirect vector control is developed. Motor currents are regulated by generating appropriate inverter output voltage vectors via software implemented comparators and switching tables. Switching tables based on angular coordinates enables the inverter to generate optimal voltage vectors. Operation principles of the proposed scheme are described and verified by laboratory tests. Both simple hardware design and good current response are obtained
