摘要:
An inductive power electronics package is disclosed. It has a circuit substrate with power inductor attached atop. The power inductor has inductor core of closed magnetic loop with an interior window. The closed magnetic loop can include air gap for inductance adjustment. The circuit substrate has bottom half-coil forming elements constituting a bottom half-coil beneath the inductor core. Also provided are top half-coil forming elements interconnected with the bottom half-coil forming elements to form an inductive coil enclosing the inductor core. An inner connection chip can be added in the interior window for interconnecting bottom half-coil forming elements with top half-coil forming elements. An outer connection chip can be added about the inductor core for interconnecting bottom half-coil forming elements with top half-coil forming elements outside the inductor core. A power Integrated Circuit can be attached to the top side of the circuit substrate as well.
