摘要： An inductor structure is combined with a ferroresonant regulator as a filter inductor in one instance, and as a regulating inductor in another. In one example, a ferroresonant voltage regulator includes a pair of shunt filters at its output to reduce the low order odd harmonic content of the AC output. The filtering arrangement includes two LC shunt filters having their independent inductor windings wound on a single magnetic core unit. Auxiliary windings coupled to each of the inductor windings are placed in series with the output to buck any remaining harmonics.In a second instance, independent regulating inductors in a multiphase ferroresonant regulator are also realized on a single magnetic structure.

摘要： A rectifier plant control system includes a stored program of a master control to control operation and monitor rectifier plant conditions. The master control is designed to cooperate with optional control systems to accomplish new operations without requiring modifications to the stored program control of the master control. One such optional control system permits accessing the master control from a remote location.The optional control system includes an associated stored program which is utilized by the master control to accomplish the option. This associated stored program is in an address field of the stored program of the master control and is executed by the master control.

摘要： A rectifier plant controller is combined with a continuously operating feeder monitor option in order to provide feeder line data on demand. The feeder monitor option continuously monitor feeder lines selected by the rectifier plant controller and stores the data acquired in a memory accessible to both the feeder monitor option and the rectifier plant controller. The rectifier plant controller can recover the data upon request at any time.
