Abstract: An electrical power generation system incorporates thermoelectric devices (TE Devices) for electrical power generation adjacent a flow path heat exchanger (HEX) adjacent to a vehicle flowpath structure such as a scramjet flow path to take advantage of the waste heat, high thermal gradients, and available, unused volume. A thermally conductive material communicates thermal energy from a vehicle external skin structure to the TE Device while a thermally conductive compliant material allows the TE Device to “float” with minimal mechanical stress.

Abstract: A power inductor assembly includes and multiple coil sections disposed upon a mounting frame. Multiple winding sections each encircle one of the multiple core sections and a portion of the mounting frame. Air gap spacers separate adjacent core sections. The arrangement facilitates removal of thermal energy from the magnetic core. Lamination build direction normal to inductor mounting surface minimizes eddy current losses.
