Refinements are needed for better correlation between chip-level or module-level measurements and whole vehicle testing. Michael Koffink and Roland Gubisch, Intertek Testing Services, Boxborough, Massachusetts, USA The automotive EMC environment is in a constant state of flux as new onboard electric devices, communications media (both wired and wireless), and new drive … [Read more...]
RF Emission Reduction Techniques for ARM-Based Microcontroller Applications
A system's immunity can be enhanced without causing any functional drawbacks. Mart Coenen, EMCMCC bv, Eindhoven, the Netherlands INTRODUCTION With today’s digital designs and the time frame available for design-in, electrical system engineers and PCB designers are more or less forced to follow the application concepts provided by embedded device manufacturers. The … [Read more...]
Shielding of an EMG Machine Utilizing a Conductive Tent
Testers seek to remedy the longstanding problem of “noisy’ responses from an EMG instrument. Terence P. O’Laughlin and Michael J. Oliver, MAJR Products, Saegertown, Pennsylvania, USA INTRODUCTION This paper presents a shielding methodology and test in which an electromyography (EMG) instrument is shielded from spurious electromagnetic and radio frequency interference … [Read more...]
The Global EMC University: 2009 IEEE International Symposium on Electromagnetic Compatibility
The Global EMC University was first offered at the 2007 IEEE EMC Symposium in Honolulu, Hawaii as a means of helping engineers who were new to EMC to get up to speed on a variety of topics that are an important part of EMC engineering. The overwhelming response to this program caused the Symposium Committee to add it to the Technical Program for the 2008 Symposium in Detroit … [Read more...]

Test Firm Acquires Swedish Lab
Well known global test firm, Intertek has announced that it has acquired from Sargentia the assets of Jäfälla, Sweden-based Sargentia Catella AB. Already known for its EMC and product safety testing, Intertek will expand its offerings and capabilities with the addition of Sargentia Catella. The Swedish organization brings to Intertek 50 years of experience in the energy storage … [Read more...]
EMC Filters for Improved Solar Reliability
The FN 2200 range of filters from Schaffner reduces conducted emissions when used with photovoltaic solar energy inverters on the DC input side. Conducted emissions toward the solar panel are reduced along with the probability of EMI radiation from the solar panel, thus preventing premature panel aging caused by HF leakage currents. When used in conjunction with the … [Read more...]
Filtered Power Entry Modules Target General/Medical Applications
New 10-amp versions have been added to Tyco Electronics’ Corcom GG series general- purpose power entry modules and HG series for medical applications. The GG series of power entry modules combines the functions of a general-purpose RFI filter with an IEC power cord connector and single- or dual-metric fuse holder. The HG medical version features reduced line-to-ground … [Read more...]
Industry Standard Metalized EMI Filters Boost Appliance Safety
The new 095 Series of filters from LCR Electronics uses a highly cost-effective metalized film technology that provides both the high reliability and fail-safe characteristics often associated with more expensive older technologies such as impregnated paper-foil. If a failure occurs, the metallization over the film evaporates, eliminating the chance of electrodes of the … [Read more...]
Cost Optimized 3-Phase Line Filter
A line of 3-phase line filters from Schurter has been dubbed series FMAC ECO and FMBC ECO. These compact and cost optimized filters are in ECO designed and especially suited for use in drive systems, engineering installations and places where frequency inverters cause electromagnetic disturbances. The EMC filters are arranged for use with 480 VAC installations and are available … [Read more...]
