Abstract: A pair of transistors are connected to opposite ends of the magnet coil to be energized. A control pulse directly turns one transistor on and simultaneously fires a single shot multivibrator and its output turns on the other transistor. Current builds up in the coil during the single shot multivibrator time out period. The transistor controlled by the single shot multibivrator turns off when the single shot multivibrator times out. Coil current decreases but at slow rate as it circulates from one side of the power supply through a diode connected to one end of the coil and through the transistor connected to the other end of the coil back to the same side of the power supply. The dropping of the control pulse turns off the other transistor and the coil current rapidly decays to zero because the power supply is connected across the coil in a reverse direction via another diode connected to the other end of the coil and the other side of the power supply.
Abstract translation: 一对晶体管连接到电磁线圈的相对端以被通电。 控制脉冲直接将一个晶体管接通，同时触发单次多谐振荡器，其输出导通另一个晶体管。 在单次多谐振荡器超时期间，线圈中的电流积聚。 当单次多谐振荡器超时时，由单发多纤维管控制的晶体管关闭。 线圈电流随着从电源的一侧通过连接到线圈的一端的二极管和连接到线圈的另一端的晶体管回流到电源的同一侧而循环。 由于电源通过连接到线圈另一端的另一个二极管和电源的另一侧在相反的方向连接在线圈上，所以控制脉冲的下降使另一个晶体管截止，线圈电流迅速衰减为零 供应。
