Abstract

This paper propose Constant Frequency CR-PWM VSI. In which ON/OFF output of Hystersis comparator, which compares the amplitude of reference current with that of actual current, control the switching elements with a constant sampling period of $\mu$-processor. Speed control system of BLDCM driven by controller wi th CF CR - PWM VSI was built.
