    At present a large range of car-to-car and car-to-infrastructure communication systems is under development. There are hardly publications about expectable EMC and spectrum management problems and some car manufacturers have not cared about these problems in early development stages. The scope of the paper is to identify and assess possible risks and to propose countermeasures. View full abstract»

    In the first part of the EMI filter design series, the conducted EMI generation mechanism was explained. In this second part, a method on the measurement of noise source impedance of SMPS will be described. The proposed measurement method allows accurate extraction of the common-mode and differential mode equivalent noise source impedances of a SMPS under it actual operating conditions.

    EMC compliance is a mandatory requirement for electronic and electrical devices export to European countries and the USA. Hong Kong is an export-oriented city with 23% of the total export in electronic and electrical products; knowledge in EMC design and standards are highly desirable to engineers in Hong Kong. To cater for these particular needs of the local industry, EMC was introduced as an undergraduate course in 1994, prior to the effective date of implementation of EMC Directive 89/336/EEC in 1996. After 15-years of development and modification, the EMC course has now become one of the most popular postgraduate courses in Hong Kong. The course includes lectures, EMC standard interpretation, case studies, together with an emphasis on the hands-on experience of EMC tests and facilities in the EMC test laboratory. In this paper, a summary of the development of the EMC course at the City University of Hong Kong in the last decade are presented, and some possible future EMC needs are discussed at the end.

  • Signal integrity: Efficient, physics-based via modeling: Principles and methods

    This article discusses the high-frequency behavior of thru-hole vias enclosed by solid reference planes in packages and printed circuit boards and reviews some efficient modeling alternatives for signal and power integrity applications. The electromagnetic behavior of vias, including the excitation of parallel-plate modes and the role of return vias, is introduced as preamble to the modeling approaches. The physics-based via model and its building blocks are then discussed. The last section reviews some improvements to the via model, covering intrinsic models for the near field of vias and the utilization of contour integral and multiple scattering methods.

    It is important to understand how your test equipment operates so you can make proper and reasonable conclusions from the indications you observe. Unfortunately, very few universities teach classes on `how equipment works' and so often students and graduates approach measurements as more of a `black box' approach and believe the measurement results simply because they believe measurements are never wrong! In truth, a measurement will certainly always provide you with an answer, but the real question is whether or not you actually got the result to the question you “thought” you were asking! This article will examine how some test equipment works and some common misuses and the resulting incorrect conclusions. View full abstract»

    This paper discusses the development of aircraft EMC from its beginning finishing with a discussion of the challenges currently facing the various standardisation committees. Aircraft EMC requirements have undergone a process of continuous change driven by the ever increasing Electromagnetic (EM) Environment, both in terms of amplitude and frequency range, and the increasing use of electronics in the aircraft systems critical functions.

  • Rail transit EMI-EMC

    Rail transit systems around the world benefit from increasingly sophisticated systems for electric propulsion, auxiliary power, control, and signaling. Applying these systems cost-effectively requires interoperability standards and testing procedures that guarantee EMC. This paper surveys the sources of EMI in rail transit from propulsion and auxiliary power systems, and the potential disruption of track signaling and train control systems that can result. U.S. and European standards for design and testing of rail transit system equipment are reviewed. Standards and test procedures for radiated interference in rail transit systems are reviewed, and EMI/EMC challenges are noted. View full abstract»

    This paper compiles similarities and differences among Automotive EMC Standards. In particular, the paper concentrates on EMC standards dedicated to testing automotive components. The paper presents an introduction of the primary automotive component standards. Based on this introduction, CISPR 25 and the ISO 11452-2 are analyzed since they are the basis for most other standards. The anechoic chamber requirements are studied in detail. View full abstract»

  • Predicting module level RF emissions from IC emissions measurements using a 1 GHz TEM or GTEM cell — A review of related published technical papers

    Publication Year: 2012 , Page(s): 91 - 96

    This paper reviews some of the many published technical papers relating to the measurement of IC emissions using a 1 GHz TEM cell or GTEM cell modified to accept an IC test board and provides a basis for correlation between these IC level measurements and module level RF emissions. We will follow the development of this methodology from the early investigations through the later applications to show the viability of the technique for IC qualification. Developments over time have shown that this method of IC emission measurement is repeatable, correlatable to other methods and provides, within limits, useful prediction of module level RF emissions performance.

    Hybrid and electric vehicle batteries are actually an Energy Storage System whose internal module functions include: battery monitoring and control, DC to DC convertor(s), an internal battery charger and internal battery cooling control. As a result, comprehensive EMC testing requires a paradigm shift from module or component level testing to complete EMC system level testing. View full abstract»
