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.[1] 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.[2]
The company's predecessor, Analytical Engineering, Inc., was founded in 1995. The company met with significant early success as the developer of simulation models and performed Worst Case Circuit Analysis on the International Space Station's power bus electronics. A series of satellite projects continued to keep founder Steve Sandler and Analytical Engineering busy, including Tempo, Globalstar, GOES, GPS, MCI, Omegasat and P-81.
In 2002, with the idea of expanding the business and the management team, the businesses of Arizona-based Analytical Engineering, Inc. and a related New York-based company, Analytical Services, Inc., were combined and purchased by AEi Systems, LLC in transactions spearheaded by Charles Hymowitz (an electrical engineer formerly of McDonnell Douglas and Intusoft) and his business partner, Lee Weinberg.
AEi Systems continues to improve its capabilities and to set the standard for performance of Worst Case Circuit Analysis, stress analysis, failure analysis and reliability analysis. AEi Systems has also expanded its digital analysis offerings and capabilities to include performance of in-depth reviews and analyses of the signal integrity and the power integrity of identified circuitry, boards and systems (in addition to Worst Case Digital Analysis).
AEi Systems has senior engineers in several United States cities.
The company has three, inter-related business lines:
AEi Systems has been involved in the development and analysis of some of the most sophisticated and technically challenging power systems in the world, both in the space and military defense arena and also with respect to commercial and industrial applications. The company provides (or uses its proprietary) computer simulation models and performs WCCA on most projects.
Many of the company's projects are for United States "classified" programs. Among the company's publicly known projects are:
AEi Systems has also been active in commercial and industrial projects that do not involve space, military or defense. For example, AEi Systems has worked on:
AEi Systems has produced robust SPICE models for many major IC manufacturers, including Texas Instruments, ON Semiconductor, Analog Devices, Linear Technology and National Semiconductor.
Since 2005, AEi Systems' modeling business unit has produced and internationally distributed its 600-model Power IC Model Library for PSpice.[7] [8]
The company has also developed a library of proprietary SPICE models (including models of space-qualified rad-hardened ICs) to support its performance WCCA services and reporting.
The company developed and taught the "six sigma" WCCA training class for Motorola University, and continues to teach WCCA techniques via on-line and on-site classes for customers.
