A transformer includes an iron core, and an inner coil and an outer coil which are coaxially mounted on an iron core limb of the iron core. The inner coil is a pancake coil; and a wire leading means of the inner coil is leading out inner lead-out wires from an innermost winding of the inner coil towards a center side of the inner coil, and a wire leading means of the outer coil is radially leading out outer lead-out wires from an outermost winding of the outer coil towards the outer side of the outer coil. According to the transformer structure, both the inner lead-out wires and the outer lead-out wires can be located at positions where the magnetic field strength is weak, such that the eddy current loss of terminals of the inner lead-out wires and the outer lead-out wires can be greatly reduced.
A transformer, comprising an iron core, an inner coil and an outer coil, wherein the inner coil and the outer coil are coaxially mounted outside an iron core column of the iron core, the inner coil is a pancake coil, and a lead-out manner for the inner coil involves drawing an inner lead-out wire from an innermost layer of windings of the inner coil towards a center of the inner coil, while a lead-out manner for the outer coil involves radially drawing an outer lead-out wire from an outermost layer of windings of the outer coil towards an outer side of the outer coil.
