Claim of US Patent No. 10,117,334

1. A magnetic assembly comprising:a first magnetic core having a first top surface, a first bottom surface, a first sidewall, a second sidewall, at least one first sidewall through-hole and at least one second sidewall through-hole, wherein the at least one first sidewall through-hole is disposed on the first sidewall, the at least one second sidewall through-hole is disposed on the second sidewall, and the first sidewall is opposite to the second sidewall;
a second magnetic core having a second top surface and a second bottom surface, wherein at least a portion of the second bottom surface of the second magnetic core is connected to the first top surface of the first magnetic core by an adhesive layer; and
at least a first series winding having a first upper winding set, a first sidewall winding set, and a second sidewall winding set, wherein the first upper winding set is disposed on the first top surface, the first sidewall winding set is disposed in the first sidewall through-hole, the second sidewall winding set is disposed in the second sidewall through-hole, the first upper winding set is electrically connected to the first sidewall winding set and the second sidewall winding set, so as to form the first series winding around the first magnetic core.
