低成本脉宽调制变频调速方案的研究

Study on a PWM Motor Speed Controller of Variable Frequency with Low Cost

介绍一种成本低廉、脉宽调制型变频调速方案,并对它作了理论分析和实验研究。结果表明,这种调速控制器比其它的简单,可用于笼型电动机较宽范围的调速。

Design of a PWM Changer of frequency with low cost is studied in this paper. The theoretical analysis and the experimental results are obtained. They show that this kind of motor speed controllers are more simple than others
