D.Attorney, Agent or FirmAbstractA first low voltage power supply having silicon controlled rectifier regulation in the primary of the power transformer, capable of supplying very high direct current, and a second well regulated feedback power supply providing a fixed current in reverse polarity are connected in parallel across a load. The first power supply is feedback controlled to maintain constant current sinking in the second power supply. The second power supply is programmed to regulate the load current or voltage, to provide fine regulation at the load, and to reduce ripple voltage at the load.Other References
