Title:
HIGHLY INTEGRATED MAGNETIC ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/109572
Kind Code:
A1
Abstract:
A highly integrated magnetic element comprises a first magnetic core and a second magnetic core each of which has at least one recess. The two magnetic cores face each other and are connected. After the two magnetic cores have been connected, the connected recesses at least form a first through hole and a second through hole. One section of the sidewall of the first through hole has a break so as to form an air gap. An inductive coil is wound around the sidewall of the first through hole. The sidewall of the second through hole is continuous and closed. A transformer coil is wound around the sidewall of the second through hole. Compared with the prior art, the present invention combines a transformer and an inductor which do not mutually interfere, has favorable heat dissipation performance, a small size, a light weight and low costs, and realizes production of multiple output voltages.
