Power Electronics Technology Applications for Future SSBNs - FY 78. Switching Mode Power Supply Designs are Compatible with Sensitive SSBN Circuits.

Abstract

The impact of switching-regulator noise on sensitive communication circuits is investigated. State-of-the-art switching-mode power supplies are shown to be compatible with sensitive receiver circuits including low-frequency receivers. Recent advances in component design and circuit design techniques that curtail or contain electromagnetic interference (EMI) in switching-mode converters are discussed. The frequency spectrums of the powerline-conducted EMI are analyzed for both ac and dc input designs. By using an optimally designed input filter, the emission caused by the switching action is shown to be less than expected new CE-03 limits for MIL-STD-461A. A major breakthrough in reducing EMI is a recently developed topology for switching-mode power supplies. Compared to dissipative power supplies, low voltage switching-mode power supplies occupy less volume, weigh less, cost less, and use less energy. (Author)
