Abstract

The present invention relates to a hybrid transformer. In a transformer comprising a primary core and a secondary coil, the hybrid transformer includes a core with a 1st leg, a 2nd leg, and a 3rd leg; and a secondary coil with a 1st winding, a 2nd winding and a 3rd winding, which are wound zigzag on said 1st leg, said 2nd leg, and said 3rd leg. Two types of windings selected from a group consisting of said 1st winding, said 2nd winding and said 3rd winding are wound alternatively on said 1st leg, said 2nd leg, and said 3rd leg, respectively. However, the two types of windings wound on said 1st leg, said 2nd leg, and said 3rd leg, respectively, are wound in an overlapping manner around said core in the winding order.

Description

technical field [0001] The invention relates to a hybrid transformer including voltage transformation function and harmonic and current unbalance improvement function and a power supply system including the hybrid transformer. Background technique [0002] Generally, a transformer (electric transformer) is a device that changes an AC voltage or current value through an electromagnetic induction phenomenon, and is directly connected to a power transmission system for use. [0003] On the other hand, due to the increase of non-linear loads brought about by the development of power semiconductors, harmonics and unbalanced currents are likely to occur in the power system. This harmonic and unbalanced current flows into the power supply side with low impedance, causing various problems such as cable overheating, increased power loss due to transformer core saturation, and malfunction of electrical equipment. [0004] In order to reduce the damage caused by the above-mentioned ha...
