Patent ID: 10326395

Abstract:
An electrical system (2) includes a transformer (16) coupled to an AC source (6) that provides a main AC voltage, the transformer having a number of sets of primary windings (18) and secondary windings (20), and a charging module (32) structured to generate a magnetizing AC voltage. The charging module is structured to selectively provide the magnetizing AC voltage to: (i) one of the number of sets primary windings, or (ii) one of the number of sets secondary windings. The magnetizing AC voltage is such that responsive to the magnetizing AC voltage being provided to one of the sets of primary windings or one of the sets of secondary windings, one or more of the sets of primary windings will be magnetized in a manner wherein a flux of the one or more of the number of primary windings is in phase with the main AC voltage provided from the AC source.
