AI Technical Summary
Existing magnetic components, while balancing inductance requirements and uniform magnetic flux distribution in the iron core, have introduced copper loss issues.
By designing the structure of the core and windings, the number of turns passing through the inner side of the winding is greater than the number passing through the outer side. By utilizing the characteristics of a single magnetic circuit core, the DC resistance is reduced and a uniform magnetic flux distribution is maintained.
This effectively reduces the DC resistance of magnetic components, decreases winding losses of copper wire, and maintains the expected inductance design.
