Abstract
A power module comprises a first circuit board assembly and a magnetic core assembly. The first circuit board assembly comprises a first printed circuit board and at least two switch circuits disposed on the first printed circuit board. The magnetic core assembly is disposed near the first printed circuit board and comprises a magnetic core portion and at least one pair of first electrical conductors. The magnetic core portion comprises at least one core unit, the core unit comprises a pair of holes and a second magnetic overlapping region, and the pair of holes are separated by the second magnetic overlapping region. Each pair of the first electrical conductors is penetrated through the corresponding pair of holes of the magnetic core portion to define two output inductors. Each of the switch circuits is electrically connected with the corresponding output inductor to define a phase circuit of the power module.
