Abstract
A transformer module and a power module are provided. The transformer module includes: a magnetic core, a first winding and a second winding. The magnetic core includes at least one magnetic column at least partially covered by a multi-layer carrier including a plurality of horizontal copper foils and connecting copper foils. Horizontal copper foils are located on horizontal wiring layers, and connecting copper foils are disposed to connect horizontal copper foils. First and second windings surround the magnetic column, and the second winding is located outside the first winding. Both the first and second windings are formed by a horizontal copper foil and a connecting copper foil; two ends of the first winding are electrically connected to first and second surface-mounted pins; two ends of the second winding are electrically connected to third and fourth surface-mounted pins; these pins are disposed on at least one surface of the transformer module.
