摘要: 提出了一种基于空间矢量的PWM算法的全数字化变频器 ,简要介绍了空间矢量脉宽调制的理论。该变频器主要由主回路和控制电路两部分组成。控制电路采用数字信号处理器TMS32 0LF2 4 0 7实现SVPWM波的输出 ;主回路中采用智能功率模块PM 10 0CSA12 0作为功率器件。该变频器在 1.5kW交流电机上进行试验 ,结果令人满意Abstract: 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.
