摘要
建立了适于控制载波比切换的异步电动机变频调速系统的仿真模型,并给出了详细的仿真模型。针对多种改变载波比的方案进行了仿真分析,仿真结果显示其他几种方案效果都不及电压过零点切换方案。为进一步做变频调速优化性能方面的研究提供了基础及方便。
A simulation model of suitable varied carrier ratio of variable-frequency adjustable-speed system of induction motor is constructed. The detailed simulation models are given. Different schemes of varying carrier ratio are studied. The result shows that the scheme of carrier ratio in zero voltage is optimization. The paper provides convenience and foundation for further studying the performance of variable-frequency adjustable-speed system.
