Title:
ACTIVE POWER TRANSFORMER FOR CONTROLLING NON-UNIFORM VOLTAGE
Document Type and Number:
WIPO Patent Application WO/2023/229057
Kind Code:
A1
Abstract:
An active power transformer for controlling non-uniform voltage, of the present invention, comprises a plurality of zigzag wiring parts that are symmetrically-structured and are connected to a power source system having three-phase wiring for supplying an alternating current power source to a load, wherein the plurality of zigzag wiring parts has a core having three legs, four windings of a three-phase transformer are wound around each leg in the same direction so as to be symmetrical to each other, a second lead wire of a winding of a neighboring phase is connected to a first lead wire of a winding for the transformer, which is wound around a leg of each phase, through a lead connection wire so as to form a terminal of each phase, and the lead wires of the remaining windings are connected to a neutral point, and the respective lead connection wires do not intersect with each other, and thus a safer active power transformer for controlling non-uniform voltage is possible.
