Research and Design of AC Speed Regulating System for SVPWM Based on DSP

An asynchronous motor has a simple structure and is reliable in operation and easy to maintain. Along with the de- velopment of electronic devices, microprocessors and control techniques, AC speed adjustment is more and more widely ap- plicable. The paper introduces the research and discussions on the variable-frequency speed control system for AC asyn- chronous motors and proposes corresponding hardware and software designs. Control chip DSP TMS320LF2407A for TI motors together with SVPWM control methods were used to regulate the speed of AC induction motors with a variable frequency, thus greatly improving the running accuracy of AC motors.
