    Abstract: Dynamic current feedback for a main motor-generator is provided by an auxiliary generator which supplies power directly to the main excitation field winding of the main motor-generator, rather than to an auxiliary shunt field winding as in a prior design, the main auxiliary generator in turn being driven by a current-follower type DC motor whose speed depends on the amount of current passing through the main motor-generator armature or the voltage drop across the main motor-generator series winding in the case of a series or compound main motor-generator. The current supplied by the auxiliary generator to the main excitation field winding of the main motor-generator can have either the same polarity as the main excitation field winding of the main motor-generator, or an inverse polarity, to provide positive or negative feedback.

    Abstract translation: 用于主电动发电机的动态电流反馈由辅助发电机提供,该辅助发电机直接向主电动发电机的主励磁励磁绕组提供功率,而不是如先前设计中的辅助并联励磁绕组,主辅助发电机 反过来由电流跟随型直流电动机驱动,其速度取决于通过主电动发电机电枢的电流量或主电动发电机串联绕组上的串联或复合主电机的电压降 -发电机。 由辅助发电机提供给主电动发电机的主励磁励磁绕组的电流可以与主电动发电机的主励磁励磁绕组具有相同的极性,或者具有相反的极性,以提供正或负的反馈。
