Abstract
High-frequency transformers using solid wire for welding-type power supplies are disclosed. An example welding-type power supply transformer includes: a first coil assembly comprising a first plurality of turns of a first solid wire wrapped around a first bobbin to form a first single-layer primary winding, and a second plurality of turns of a second conductor over the first plurality of turns to form a first single-layer secondary winding; a second coil assembly comprising a third plurality of turns of a second solid wire wrapped around a second bobbin to form a second single-layer primary winding, and a fourth plurality of turns of the second conductor over the third plurality of turns to form a second single-layer secondary winding; and first and second cores disposed at least partially within the first and second bobbins.
