Design of Asynchronous Motor Vector Control Frequency Converter Based on DSP

Abstract

This design of the asynchronous motor frequency converter system is based on the use of fixed-point DSP TMS320F2812 controller, take voltage space vector pulse-duration modulation (SVPWM) as the control method, the full text take the frequency changer system hardware design and the software realization as the leadership, and introduced in detail the hardware electric circuit several essential electric circuits, software part SVPWM principle and realization, finally has carried on the result simulation confirmation. The simulation results show that this system speed of response is quick, the stability is good, has the good static state, the dynamic performance.
