摘要
分析了空间矢量脉宽调制基本原理,探讨了一种三相电压型逆变器空间矢量PWM的改进算法。该算法比传统算法简易,在驱动异步电机系统中产生较小的开关损耗。在基于DSPTM S320F2812三相异步电机控制系统上编制了空间矢量PWM的软件,并进行试验,给出了相应的试验结果。
The principle of space vector PWM is analyzed. An algorithm of space vector PWM for three-phase voltage fed inverter is discussed. This algorithm is simpler than the traditional algorithm, and less switch losses arise in the asynchronous motor system. Software of the space vector PWM are compiled and tested based on DSP TMS320F2812 control system of the three-phase asynchronous motor. Test results are listed.
