Development of SVPWM Frequency Converter Based on DSP

The paper presented a full digital frequency converter based on a control algorithm of space vector pulse width modulation (SVPWM). The theory of SVPWM was discussed in brief. The frequency converter consists of main circuit and control circuit. The output of SVPWM wave was realized by the digital signal processor TMS320LF2407. The main circuit took the intelligent power module PM100CSA120 as power devices. The results of experiment on a 1.5 kW AC motor were satisfied.
