Methods of manufacturing inductor modules and power semiconductor systems having inductor modules

A method of manufacturing inductor modules, the method comprising:

• embedding a ferrite sheet in an insulating material, the ferrite sheet having a plurality of elongated openings;
• laminating first and second metal sheets onto the insulating material over opposite sides of the ferrite sheet to form a panel;
• forming holes through the first and the second metal sheets and the insulating material, the holes being aligned with the elongated openings in the ferrite sheet;
• plating the holes with metal to form electrically conductive vias that extend between the first and the second metal sheets;
• patterning the first and the second metal sheets to form metal traces which are electrically connected by the vias;
• and
• dividing the panel into separate printed circuit boards, each printed circuit board including an inductor module.
