【Abstract】 By using of Intel 80c196MC microprocessor the method of realization to produce SPWM wave form at high frequency was introduced which is based on the principle to follow the trail of magnetic flux linkage according to the electro-magnetic characteristics of induction motor ,and the qualitative and quantitative analysis was carried out. An algorithm and practical output wave form were given. The experimental results verified the validity of the method.更多还原
