Margin is an important index in the control of Electromagnetic environmental effects (E3) and compatibility (EMC) design for systems. How to define verify E3 margins complex systems such as ships airplanes a difficult problem. A new method system-level margin evaluation proposed. Based on theory fault tree, model constructed. The system function transformed into equipment subsystem that affect ...

Abstract Converter valve is the key equipment of power grid, safety and reliability deeply affect grid. In industry, infrared discharge sensors have been widely used to realize on-line condition monitoring. However, devices’ failure accuracy reduced often happen, complex electromagnetic environment caused by converter are difficult resisted. It necessary study interference produced in order gui...

Abstract Operating a radio-frequency ion thruster (RIT) requires high frequency current flowing through an induction coil in order to ignite and maintain inductively coupled plasma discharge (ICP). Several methods create that have been demonstrated evaluated regarding complexity, flexibility efficiency. Especially space applications reliability minimal power loss is crucial comply strict missio...

In 2015, the energy measurement of some static electricity meters was found to be sensitive specific conducted electromagnetic disturbances with very fast current changes caused by highly nonlinear loads, leading meter errors up several hundred percent. This article describes new results on compatibility (EMC) 16 different from all over Europe when exposed real-world disturbance signals. Those ...

Hiroki Funato, Dr. Eng. Jia Li, Dr. Eng. Masayoshi Takahashi, Dr. Eng. Isao Hoda Hideyuki Sakamoto Ryuichi Saito OVERVIEW: To ensure vehicle safety and comfort, there is a need to minimize interference due to electromagnetic noise from automotive electronics. While automotive manufacturers have stipulated EMC standards for this purpose that component suppliers are obliged to comply with, there ...

Power converters are an essential part of modern power systems, giving flexibility to the transportation and allowing insertion a wide range different energy sources. One drawback is that supraharmonic conducted emissions introduced by them can compromise stability these systems through electromagnetic interference (EMI). Electromagnetic compatibility (EMC) filters used prevent such problems. N...

The typical radiating power levels of the DVB-H sites are normally between the values used in mobile and television broadcast networks. It is thus important to take into account accordingly the EMC (Electro Magnetic Compatibility) as well as the human exposure limits in the DVB-H transmission facilities. This paper presents a practical method for estimating the safety limits of human exposure a...

|This paper presents the investigations in the electric performance of di¬erential signalling transmission lines used for high speed integrated circuits (IC’s) and boards by using the parallelized ­ nite-di¬erence time-domain (FDTD) method. The FDTD method is ­ rstly parallelized with single-program multipledata (SPMD) architecture using the MPI protocol and experimentally validated. The key el...

Classification algorithms often handle large amounts of labeled data. When a label is the result of a very expensive computer experiment (in terms of computational time), sequential selection of samples can be used to limit the overall cost of acquiring the labeled data. This paper outlines the concept of sequential design for classification, and the extension of an existing stateof-the-art res...
