  • INDUCTOR DEVICE
    Publication number: 20240087799
    Abstract: An inductor device including a frame portion, a first winding set, a second winding set and a first common magnetic core I piece is provided. The first winding set, the second winding set and the first common magnetic core I piece are disposed in the frame portion. The first common magnetic core I piece substantially connects the first winding set and the second winding set and the frame portion. The material of the two winding sets is different from that of the first common magnetic core I piece.

  • TRANSFORMER
    Publication number: 20230230748
    Abstract: A transformer includes iron cores and a winding structure. The iron cores are stacked on each other at intervals, and iron core gaps are formed between the iron cores, wherein relative positions between the iron core gaps are fixed. The winding structure is disposed around the iron cores and includes a plurality of coils. A position of at least one of the iron core gaps corresponds to a position of at least one of coils.

  • Adjustable leakage inductance transformer
    Patent number: 11489449
    Abstract: An adjustable leakage inductance transformer includes a magnetic core, a primary side coil and a secondary side coil. The magnetic core includes a magnetic core column structure, which has a central column, a first outer column and a second outer column. The primary side coil is wound on the first outer column and the second outer column by a first primary side coil loop number and a second primary side coil loop number, respectively. The secondary side coil is wound on the first outer column and the second outer column by a first secondary side coil loop number and a second secondary side coil loop number, respectively, the first primary side coil loop number is not equal to the first secondary side coil loop number, and the second primary side coil loop number is not equal to the second secondary side coil loop number.

  • Transformer and series resonant converter including the same
    Patent number: 11171561
    Abstract: A transformer includes a magnetic core, a primary side winding and a plurality of secondary side windings. The magnetic core includes a first outer column, a second outer column, an upper cover and a lower cover. The first outer column and the second outer column are disposed between the upper cover and the lower cover. The primary side winding is disposed on the first outer column and the second outer column, and the plurality of secondary side windings are disposed on the first outer column and the second outer column. Each of the secondary windings has one end passing through a region between the first outer column and the second outer column.
