1: INTRODUCTION

Navy program reviews and fleet experience throughout the 1970s
consistently revealed that the most serious and prevalent
reliability problem with electronic systems was power
supplies. In late 1979, the Deputy Chief of Naval
Material for Reliability, Maintainability, and Quality
Assurance requested from each Systems Command a list of
power supply manufacturers among its contractors and
their suppliers. A subsequent letter to some 170 companies in
1980 highlighted the Navy's concern and sought assurance that
adequate attention was being given to power supply
reliability in accordance with the Navy's then-new
reliability initiatives.

The industry replies to that letter pointed up four major problem
areas: inadequate design analysis and derating;
inadequate manufacturing screening; late design
specification; and unqualified low bidders. The Navy
responded by convening a Navy/Industry Power Supply
Conference in Washington on 2 April 1981 to discuss these
problems and their potential solutions. The proceedings of this
conference made it clear that the power supply problem was
not a simple one and would require continuing effort to
resolve.

Following the April 1981 conference, the Navy chartered a
Navy/Industry Power Supply Ad Hoc Committee staffed by technical
experts to identify the best design practices and
manufacturing processes for low-voltage switching-mode
power supplies. This committee met several times over
the course of a year, and provided the information
contained in the 1982 publication. As the technology of
both power supplies and electronics in general continued to
advance, it became necessary to update the guidelines of the
original publication. This also provided an opportunity to
address the problems of high-voltage switching-mode
power supplies, whose unique design and manufacturing
requirements are not fully addressed by the guidelines
of low-voltage systems. The original Navy/Industry Power
Supply Ad Hoc Committee was reconvened and augmented by
consultants in high-voltage technology. This revised and expanded
publication is the result of the work by this enlarged
committee over a two-year period.

The Navy wishes to acknowledge both the original and the new
committee members and to express appreciation to them and
their affiliation for their extensive contributions.
Chairman of both committees is Donald Hornbeck. Industry
members of the original committee included Gwinn Almond,
Anthony Annunziato, Dwayne Attaway, Richard Blake,
Gerald Brode, Joseph Craddock, John Donnelly, Jerrold
Foutz, Myron Pogue, and Tony Wilson. Navy members included Randy
Collins, Bud Gibson, John Jentz, and Douglas Patterson. The
committee secretary and editor was Elwood
Padgett.
