MIL-HDBK-241B, Design Guide For Electromagnetic Interference Reduction in Power Supplies, 30 September 1983.

This handbook offers guidance to power supply designers in techniques which have been found effective in reducing conducted and radiated interference generated by power supplies. It is a compilation of information from library sources, pertinent military laboratory programs including contracts to universities and industry, and practical fixes derived from the experience of engineers. Topics related to power supplies include selection criteria, power conversion approaches, off-line switching-mode power supplies, potential problems, and dc-to-dc converter topologies. Topics related to EMI associated with ac to dc rectification include basic rectifier action, rise/fall time effects, problems with excessive harmonics, and standard solutions. Topics related to EMI from switching-mode conversion include power line conducted differential-mode noise, ripple on output leads, suppression of internally radiated noise, and future low-noise designs. Topics related to components and circuit design include semiconductor switching devices, capacitors, inductors, transformers, ferrites and ferrite beads, conductors, resistors, mechanical contact protection, additional filter considerations, shielding, and reliability and EMI. Appendix B discusses the "Middlebrook Criteria" for preventing input-filter oscillations in switching regulators. 174 pages.

NAVMAT P-4855-1, Navy Power Supply Reliability, Design and Manufacturing Guidelines, December 1982.

Original version later revised as NAVMAT P-4855-1A, January 1989.

NAVMAT P-4855-1A (NAVSO P-3641), Navy Power Supply Reliability, Design and Manufacturing Guidelines, Revised Including High Voltage, January 1989 (Stock No. 0518-LP-204-4800).

The purpose of this document is to define (1) guidelines for Navy and contractor program managers and (2) design and manufacturing fundamentals for power supply engineers, that will result in power supplies which meet or exceed the reliability requirements.

The information contained in Sections 3 and 4 applies primarily to low-voltage power supplies delivering up to 5 kilowatts and 300 VDC or less. Some topics, such as output power density have been tailored for power supplies below 1,500 watts and outputs of less than 28 VDC. The unique requirements of high-voltage power supplies, those whose output voltage exceeds 300 VDC, are addressed in Section 5. While these guidelines do not directly address other power conversion equipment, such as frequency changers, inverters, uninterruptable power supplies, or static switches, precepts contained herein, such as component deratings and environmental stress screening, can be applied. Consideration will have to be given to development schedules, volume and weight, to take into account the complexities of the other types of equipment.

Modern Navy system requirements dictate that most power supplies in new equipment be of the switching-mode type. For this reason, the switching-mode assumption is implicit throughout the document.
