US 2018/0122562 A1 · POWER MODULE AND MAGNETIC COMPONENT THEREOF

Abstract

A power module including a power device and a magnetic component is provided. The magnetic component is stacked with the power device and a vertical projection of the magnetic component is at least partially overlapping with the power device. The magnetic component includes a magnetic core and a winding set. The magnetic core includes a first surface, a second surface and at least one window. The window is located between the first surface and the second surface, and includes a passing-through axis vertical to a surface of the power device, where at least one leading pin or pad is disposed on the surface of the power device. The winding set includes at least one winding portion. The winding portion passes through the window and electrically connected to the power device. Each winding set and the magnetic core are configured to form an inductor, and the winding set is preformed.

3 more elements

A magnetic component of a power module, comprising:

a magnetic core, including a first surface, a second surface and at least one window, wherein the first surface is opposite to the second surface, and the at least one window is located between the first surface and the second surface and passes through the magnetic core;
and
at least one winding set, including plural winding portions and at least one first joint part, wherein each of the plural winding portions includes a first end and a second end, and the first joint part is connected with all of or a part of the first ends of the plural winding portions and extends along the second surface of the magnetic core so as to make the at least one first joint part serve as a first leading pin or pad of an inductor of the power module, wherein at least one of the plural winding portions passes through the at least one window to make the second end of the at least one of the plural winding portions serve as a second leading pin or pad of the inductor of the power module, wherein the first joint part of the winding set and the plural winding portions are formed in one piece.
