AEi Systems is a United States space and power electronics engineering firm headquartered in Henderson, Nevada with engineers in several United States cities, including a significant subsidiary engineering center in Los Angeles, California.

Contents

AEi Systems is most well known for its analysis of space-bound and other industrial power supplies and power systems—especially those that must operate reliably under extreme conditions (such as radiation, magnetic fields, heat, and the like) and yet also keep within size and weight limitations.

AEi Systems is the world leader in Worst Case Circuit Analysis (WCCA) and failure and reliability analysis for space-bound DC-DC converters, and AEi Systems engineers are recognized as Subject Matter Experts by Aerospace Corporation in connection with WCCA and the setting of WCCA standards.

History

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 International Space Station's power buss 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. Analytical Engineering provided computer simulation models and worst case circuit analysis on most projects.

In 2002, with the idea of expanding the business and the management team, the businesses of Analytical Engineering, Inc. in Arizona, and a related company, Analytical Services, Inc. in New York, were combined and purchased by AEi Systems, LLC and moved to Los Angeles in transactions spearheaded by Charles Hymowitz (an electrical engineer formerly of McDonnell Douglas and Intusoft) and his business partner, Lee Weinberg.

Since 2002, AEi Systems has continued its growth in Worst Case Circuit Analysis ("WCCA") (also called "Worst Case Analys or "WCA") and failure and reliability analysis for space-bound DC-DC converters. In addition, the company has expanded its digital analysis capabilities, including signal integrity and worst case digital analysis.

Divisions/Organization

The company has three, inter-related business lines:

  • Analysis: Worst Case Circuit Analysis (WCCA) and failure and reliability analyses; signal integrity and other digital analyses.
  • SPICE Modeling: Modeling of complex integrated circuits for major manufacturers and to support AEi Systems analysis and design work.
  • Software: Sale of licensed copies of (i) the company's Power IC Model Library for PSpice, and (ii) WCCA templates and tables.

    • Noteworthy achievements and facts

  • Motorola University's "six sigma class" on worst case analysis was created by AEi Systems
  • AEi Systems performed important work on the LVPS power supply for the Atlas Experiment at the Large Hadron Collider (LHC) at CERN (the world's largest and most powerful particle accelerator that revealed the Higgs Boson).
  • AEi Systems has worked on analyses of several critical components of the GPS IIF and GPS III programs.
  • Most SPICE models for Power ICs that electrical engineers find on the Internet were created by AEi Systems, including those found on the websites of ON Semiconductor and Texas Instruments and used via National Semiconductor's (now Texas Instruments') online WEBENCH tool
  • AEi Systems analyzed the power buss for the International Space Station

    • Defense and Aerospace Projects

    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 defense arena and also with respect to commercial and industrial applications. The company has provided computer simulation models and worst case circuit analysis on most projects. While many of the company's projects are for classified programs, among the company's publicly known projects are:

    Commercial and Scientific Projects

    AEi Systems' power supply analysis and design expertise has also been sought for commercial and industrial projects not involving space or defense. For example, AEi Systems has worked on:

  • Darwin, a Schilling Robotics 100 kW Remotely Operated underwater Vehicle (ROV) that operates underneath the North Sea under 17 kPSI at over 6 kM
  • The Atlas Experiment at the Large Hadron Collider (LHC) at CERN, the world’s largest and most powerful particle accelerator that revealed the Higgs Boson
  • Projects for DeLL and EMC
  • Projects involving international security systems
  • Time-sensitive projects involving nuclear power plants

    • SPICE Modeling

    AEi Systems provides SPICE models to many major IC manufacturers, including Texas Instruments, ON Semiconductor and National Semiconductor.

    Since 2005, AEi Systems' modeling business unit has produced and distributed the Power IC Model Library for PSpice, which is distributed by Cadence's sole North American distributor (EMA-EDA) in the United States and Canada, and by other major distributors in Asia and Europe.

    WCCA Training and Support

    The company developed and taught the "six sigma" WCCA training class for Motorola University, and continues to teach WCCA techniques via on-site classes for customers as well as several LA-based workshops.
