Generator load response control

摘要

A voltage regulating system for a generator that supplies the battery and electrical loads on a motor vehicle. The system includes a load response control for detecting whenever a substantial electrical load is applied to the generator tending to cause a drop in generator output voltage and when such a condition is detected field current is controlled to gradually increase field current from some value. The load response control includes means for storing an electrical signal that corresponds to generator field current and for utilizing this stored value to set generator field current at a value corresponding to a field current that occurred just prior to the detected drop in voltage and then increasing field current slowly from this value. The system includes means for preventing a subsequent drop in detected load voltage from actuating the load response control for the time duration that field current is being slowly increased by the load response control once it has been triggered by an initial drop in voltage.
