Abstract
A load management system utilizing a three phase solid state inverter for applying a ripple signal on a high voltage line with the system having means (a) for conducting backfeed current from the line through a portion of the inverter, (b) for balancing the current and phase distribution through an isolation transformer, (c) for selectively sequentially connecting and disconnecting the transmission of the ripple signal from the high voltage line, (d) for providing a wide angle of conduction to assure conduction of the solid state devices over a wide time period to avoid current imbalance and core saturation.
