ABSTRACT:
For improving efficiency of a power device having an exposed surface capable of radiating energy, a shielding layer is disposed in between the exposed surface and a conductive layer. The shielding layer causes at least a portion of the energy to be directed back into the power device, thereby substantially preventing the energy from inducing eddy currents in the conductive layer. The conductive layer is fabricated from a metal foil for compliance with electromagnetic energy leakage regulations.
