Abstract

：A new method forming SPWM wave in AC variable frequency speed-governing system controlled with computer is presented in this paper. This paper explains the principle of the method, analyzes the calculating workload and the precision as using the method to produce the SPWM. The results showed the method improved the regular sample and increased precision at sampling, the on-off dot more approaches natural sampling.
