Abstract

A power module package structure is disclosed. The control circuits are fabricated on a circuit plate, instead of fabricating them directly on a main substrate. The fabrication cost is reduced because the size of the substrate is shrunk. Furthermore, the power chips are placed on a material with high thermal conductivity. The heat produced from the power chips can be transmitted quickly. Thus, the reliability of the power module package can be improved.
