数字式触发电路的研究

Research on the Digital Flip flop Circuit

提出了一种新型的变频器触发电路数字式触发电路，其变频器为无环流型，电网自然换流，功率可双向传递的静止变频器；控制电路为多微机全数字式交交变频同步机矢量控制系统。此触发电路所需要的信号为三相交流电流过零信号，该信号分别送入系统的１＃～３＃从机的高速输入口，在计算机内部进行运算，然后由高速输出口发出相应的触发脉冲。

The paper proposes a new type of flip flop circuit with a frequency converterthe digital flip flop circuit. The frequency converter is a stationary frequency converter with no circulation pattern, with naturally current converting electric network and the power transmitting bidirectionally. The controiling circuits are the vector controlling system with multimicrocomputers full digital synchronously alternating frequency converters. The signals this flip flop circuit requests are the ones of alternating current with three phases, passing through the zero in the system. These signals are respectively transmitted to 1 #￣3 # from the high speed input entrance, being calculated inside the computers, followingly, with corresponding triggered pulses to be sent out from high speed exit.
