ABSTRACT:
A bank of storage batteries is maintained in a fully charged state by a charging circuit coupled by a controlled, battery energized inverter to AC load lines to which the charging circuit and an AC source are connected. Charging current is controlled in accordance with the load current in the load lines through the primary windings of transformers in the charging circuit and applied to the batteries at a voltage level slightly higher than the full standby battery voltage. Application of full battery voltage to the AC load lines is delayed during a timed start-up period.
