AEi Systems

AEi Systems is a space and power electronics engineering firm based in the United States that concentrates on circuit, systems and design analysis.

AEi Systems specialises in Worst Case Circuit Analysis (WCCA) of critical space-bound circuitry, boards and components, including power supplies and power systems. Such specialized analysis often informs changes and updates to designs that have previously been deemed flight-ready.

The company is well known for its deep analysis of space-bound DC-DC converters and other industrial and commercial power supplies and power systems — especially those that must operate reliably over long periods of time (often under extreme conditions that include combinations of radiation, magnetic fields, heat, cold, and the like). Analyses often performed by AEi Systems include stress analysis, failure analysis, and reliability analysis, in addition to WCCA .

AEi Systems also has significant digital analysis offerings and capabilities in signal integrity, power integrity, and Worst Case Digital Analysis.

AEi Systems engineers are recognized by Aerospace Corporation as WCCA Subject Matter Experts. AEi Systems WCCA Subject Matter Experts worked with Aerospace Corporation to draft and set the current standards for WCCA of high reliability (or "hi-rel") circuitry.
