Patent Images
1. A power converter, comprising:
- a first circuit having an input adapted to receive a power source having a first voltage, and adapted to convert the first voltage to a second voltage provided to an output, the first circuit adapted to power a portable electronic device; and
a second circuit coupled to the first circuit and adapted to identify if the power source is an aircraft power source by detecting a mechanical member displacement;
wherein the power converter further includes a plug adapted to couple to the aircraft power source and having a displaceable member; and
wherein the displaceable member is adapted to be depressed upon coupling of the plug to the aircraft power source.

Abstract
A power converter having an aircraft power source detector adapted to limit the amount of power that can be drawn by the power converter when utilized in an aircraft. The power converter may detect an artifact of the aircraft power source, such as the 400 Hz ripple noise on an aircraft power line, or existing in the aircraft cabin, such EMI or aircraft lighting.
