Abstract
A power converter assembly is provided and includes high quality factor (Q) shield-to-transistor integrated low-inductance capacitor elements to divert common mode (CM) currents, high Q shield-to-shield integrated low-inductance capacitor elements to compliment line-to-line filter capacitors and high Q baseplate integrated low-inductance capacitor elements to attenuate residual CM currents.
Claims11
An integrated converter of an antenna power system, the integrated converter comprising:
- a baseplate;
- a transformer area interposed between input and output sections, the transformer area comprising:
- a magnetic core top portion;
- a magnetic core bottom portion disposed on the baseplate;
- a magnetic core pillar extending between central sections of the magnetic core top and bottom portions;
- and
- successive layers of shield and magnetic core materials, windings and magnetic core materials and shield and magnetic core materials interleaved between dielectric material layers at opposite sides of the magnetic core pillar.
A method of forming an integrated direct current (DC)/DC converter, the method comprising:
- laying down, in an input section, first and second layers of interleaved input section shield materials with layers of dielectric materials interleaved between the first and second layers of interleaved input section shield materials;
- laying down, in an output section, first and second layers of interleaved output section shield materials with layers of dielectric materials interleaved between the first and second layers of interleaved output section shield materials;
- assembling, in a transformer area between the input and output sections, a magnetic core pillar between top and bottom magnetic core portions;
- surrounding the magnetic core pillar with magnetic core pillar dielectric materials;
- and
- interleaving, in the transformer area, layers of dielectric materials with layers of magnetic core materials with windings, extensions of the first layers of input section shield materials or extensions of second layers of output section shield materials at opposite sides of the magnetic core pillar and the core pillar dielectric materials.
