摘要
本文从逆变器输出函数的Fourier分析开始,根据感应电动机等值电路的基本原理,在考虑频率变化对电机参数影响的情况下,对当前采用的变频调速的各种控制方式及输出特性进行了分析和计算。利用计算结果,可以分析电机的运行性能,也可以作为系统设计和电机参数设计的依据。
Various control modes and output characteristics for frequency control system have been analyzed and calculated in the paper, based on the Fourier's analysis of inverter output function and the basic principle of the equivalent circuit of induction motor. In the analysis and calculation, the influence of frequency changing on motor parameters have be en taken into account.The result of the calculation can be applied in analyzing the operation characteristics of motor,and be taken as the basis of system design and motor parameter design
