Title: ELECTRIC CHARGING SYSTEM AND METHOD
Abstract:
An electric charging system for a vessel, vehicle, or aircraft comprises one or more energy storage modules (97) on the vessel, vehicle, or aircraft; a pulse rectifier (105); a converter (106); and a voltage control transformer (91). The one or more energy storage modules (97) are connected to outputs of the pulse rectifier. The voltage control transformer (88) is connected to inputs of the pulse rectifier (105). The voltage control transformer comprises a serial transformer (91) having a plurality of pairs of transformer windings, connected together in series, one winding (103) of each pair being adapted to be connected between the pulse rectifier (105) and an input from an energy source and the other winding (104) is connected to the converter (106).
