A device for directing electrical input pulses onto one or two output lines , depending upon the presence or absence of a predetermined accompanying control pulse 一种装置,根据是否出现一个预先决定的伴随控制脉冲,把电输入脉冲导向到一条或两条输出线路上。
Abstract : the experimental research of edm process of conductive engeering ceramics using a special power supply by controlling pulse discharging energy , is discussed 文摘:通过专用脉冲电源脉冲放电能量的控制,进行了导电性工程陶瓷材料的电火花放电加工试验研究。
The final results in the form of control pulses are output to servo system in order to drive the stepper motors , simulating the milling procedure of numerical control tool machine 最终将处理结果以控制脉冲形式输出给伺服系统,以控制步进电机的进给,达到模拟数控机床加工的目的。
Up to now , the normal control mode for smart power integrated circuit ( spic ) has pwm and pfm . pwm bases on cfvw ( constant frequency variable width ) control pulse , whereas , pfm bases on cwvf ( constant width variable frequency ) control pulse 迄今,智能功率集成电路( spic )习用控制模式为恒频变宽( cfvw )的脉宽调制模式( pwm )和恒宽变频( cwvf )的脉频调制模式( pfm ) 。
