摘　　要：介绍了一种改进后的新型起动异步电动机用的磁控式可控电抗器的基本结构和工作原理。从数学分析出发得到等效电路,基于M atlab/PSB对其作了动态仿真。仿真表明将两个相同的变压器一次侧绕组串联,二次侧绕组反串联,可以准确地反映主回路的电流波形和控制回路的电压波形。The basic structure and operation principle of a new improved magnetically-controlled reactor for induction motor starting is introduced. Equivalent Circuit is obtained by mathematical analysis. Dynamic simulation is carried out based on Matlab/PSB. The simulation result presents that the current waveform of main circuit and voltage waveform of control circuit can be accurately reflected by two same transformers of primary winding series and secondary winding series-opposition.
