PREFACE

[

In response to requests from industry and government, the Navy
has distributed 18,000 copies of the original NAVMAT
P4855-1 since its publication in 1982. As a result of
its low-risk design and manufacturing guidelines and
their implementation by industry, low-voltage
switching-mode power supplies used in most military
electronics are no longer high risk. Unlike conditions prior to the
early 1980s, today's program and design reviews seldom
highlight concerns relative to low-voltage
switching-mode power supplies.

On the other hand, high-voltage power supplies have remained a
concern because they have not yielded to the same
techniques used for low voltage. To address their unique
requirements, as well as to update the low-voltage
guidelines, I reconvened the original committee. Aided
by additional industry experts, particularly in the
high-voltage arena, the committee members have brought this
publication up-to-date and have added design and manufacturing
guidelines for high voltage.

Power supply technology is making rapid strides. I encourage
readers to continue keeping my office informed of any
developments which ought to be acknowledged in future
revisions of this publication. I am convinced that with
continued assistance and cooperation between the Navy
and industry on power supplies and other technical
issues concerning the design and manufacture of reliable
products, we will meet the ultimate objectives of
significant improvement in Fleet readiness and reduced life cycle
cost.
