Methods to reduce DC losses in windings
Reduce the DC losses of the windings:
1. Use conductors with low resistivity to make transformers, generally copper enameled wires are used, and copper-clad aluminum enameled wires or aluminum enameled wires are not used as much as possible.
2. When the area of the transformer window allows, try to use an enameled wire with a larger equivalent cross-sectional area (a single wire should not exceed the penetration depth, which will be analyzed later)
3. Appropriately reduce the number of turns of the winding (will increase the iron loss), use with caution
Definition of skin effect:
The skin effect, also known as the skin effect, is a phenomenon in which the current density in the edge part is large and the current density in the center part is small in the conductor cross section when the conductor passes through the alternating current.
