About the transducer between rotor and power source , the paper uses a cycloconverters , comprising 36 thyristors , and analyzes the control of circumfluence , the method of cosine crossing , the producing of trigger pulse , zero current detecting , commutating logic control and its mathematical model 对双馈电机转子侧所接变频器类型，本文也进行了对比分析，对选用的循环变流器的原理还作了进一步的分析，包括环流控制方法、余弦交截法原理、触发脉冲产生、零电流检测和换向逻辑控制等部分，并给出了其数学模型。
At the same time the principles of triggering pulse to the three - phase thyristors is discussed , and a way using monostable multivibrator to produce the pulses has been given below . the hardware control system based on tms320f240 is designed , which includes sampling circuit , protective circuit , phase - compensated circuit and so on 对三相晶闸管控制电抗器的触发脉冲产生原理进行了分析，采用单稳态触发器实现六相触发同步；设计了以tms320f240为控制核心的硬件控制平台，包括采样电路、保护电路、六相触发同步等外围电路。
