Abstract
A high-frequency transformer includes: an iron core, primary windings and secondary windings, wherein the iron core is of an integrated equilateral triangle structure, the primary windings and the secondary windings are uniformly wound around three sides of the iron core, and the primary windings and/or the secondary windings are symmetrically distributed on the three sides.
Claims8
A high-frequency transformer, comprising:
- an iron core, primary windings and secondary windings;
- wherein the iron core is of an integrated equilateral triangle structure, wherein the integrated equilateral triangle structure avoids air gaps caused by splicing the iron core;
- and
- the primary windings and the secondary windings are uniformly wound on three sides of the iron core, and the primary windings and/or the secondary windings are symmetrically distributed on the three sides;
- wherein the secondary windings and the primary windings are concentrically wound on the iron core, and the primary windings are arranged outside the secondary windings;
- wherein the primary windings wound on the three sides of the iron core are respectively configured for three-phase input;
- and
- the secondary windings wound on the three sides of the iron core are of a series or parallel structure and are configured for single-phase output.
