Protection of a power system’s electrical equipment from a high-altitude (more than 30 km) nuclear explosion (HEMP) impact is a challenging issue, which until recently has not received proper attention. The fact is that HEMP does not affect people directly, while the electromagnetic pulse resulting from this explosion is a powerful devastating factor for the power grid’s … [Read more...]
4KW S Band SSPA for Satcom Uplink
Empower’s model 2176 is a compact high power GaN on SiC solid state CW amplifier. Standing 27 inches tall, it’s less than half the size of the typical legacy uplink HPA’s that it replaces. The slightly broader band brings flexibility to transmit in either of the two uplink channels. Besides the dramatic size reduction, the upgrade from legacy design to a next generation SSPA … [Read more...]

Review of MIL-STD-1275 Requirements
Introduction This may seem disassociated from the electromagnetic compatibility (EMC) theme of this publication but issues dealing with power quality and the qualification testing has a direct link to EMC. Frequently the EMC engineers and technicians are tasked taking care of the power quality, so I believe that reviews of these standards are appropriate. MIL-STD-1275 deals … [Read more...]
HEMP Protection Strategy for Power System’s Electronic Equipment
Annotation The issue of protecting electronic equipment from the electromagnetic pulse of a high-altitude nuclear explosion is very relevant and important for the power industry. Current knowledge about individual HEMP protection elements, their specifications and application features is very important, but, at the same time, limited to ensure efficient protection of power … [Read more...]
Review of MIL-STD-1399-300-1 Requirements
Introduction The electrical power system of a ship functions like a city’s electrical grid from the power generation to medium voltage distribution to the low voltage networks located in various sections of the ship’s structure. It only makes sense to treat the power system like a city’s power system, after all larger vessels include services that a city would … [Read more...]

Is Electric Equipment Grounding the Basic Protection Means Against HEMP?
Abstract The article discusses the differences between the electromagnetic pulses at lightning (LEMP) and at high altitude nuclear explosion (NEMP or HEMP). The article also shows that these differences do not allow to transfer LEMP experience on to NEMP. The author questions the effectiveness of grounding of electronic equipment as the main protection principle against … [Read more...]
Be Careful with Low Cost/Quality Common Mode Chokes ….
Dear readers, I have been really busy working in training and EMI troubleshooting in the past months. I am happy to be here again with a new post. This month we will see a topic from a real-world situation - very interesting - for electronic designers working in conducted emissions problems. In one of the projects I was involved with several weeks ago, a product was … [Read more...]
