When correctly applied, real financial savings can be expected, along with a significant reduction in financial risks. Keith Armstrong, Cherry Clough Consultants, Stafford, UK Electronic complexity is increasing with no end in sight, increasing self-generated noise levels, while the feature sizes in silicon integrated circuits continue to shrink, making them emit more noise … [Read more...]
2010 Update on IEMI and HEMP
INTRODUCTION It has been three years since the state of the art dealing with IEMI and HEMP has been updated in the Interference Technology Annual EMC Guide in 2007 [1]. A significant amount of work has been accomplished worldwide during this period. This paper will review significant special sessions and tutorials at International EMC Conferences, published papers and reports, … [Read more...]
Protection of Variable Speed Drives Utilizing the Cascade Protection Approach
In today’s competitive industrial environment, maximization of operations is essential, and companies cannot risk system malfunction or potential failure due to power disruptions. The end result can be disastrous, ending in loss of production, profits, clientele, and ultimately, complete operational failure. This makes the quality of power of vital importance. Consequently, … [Read more...]
COTS Alternatives to MIL SPEC Flexible Conduit Systems for EMI/RFI Containment
Applications, electrical and physical performance, termination and installation factors of shielded flexible conduits. Linda Sardone, Zero Ground Electronic solutions for military and government equipment and installations are expanding rapidly, and the need for supplemental shielding of cable runs via conduit is moving beyond traditional applications requiring MIL SPEC … [Read more...]

Auto Safety Bill Includes Standard for Electronic Controls
Broad automobile safety legislation introduced by the Senate on Tuesday would set new standards for electronic controls, stopping distance, push-button ignition systems and data recorders. The legislation follows the recalls of more than nine million Toyota vehicles worldwide since the fall, including two major recalls for problems with sticking accelerator pedals. It also … [Read more...]
Reinventing Compact Immunity Testers
In the dim and distant days of the last century, EMC emerged relatively late on the evolutionary scale. Although engineers “of a certain persuasion” were laying the foundations as far back as the early 1960s, it was not until the European Union decided on a common identification mark (CE) to be a legal requirement in December 1994 that EMC became mainstream among test … [Read more...]
NHTSA is Behind Times on Car Electronic Safety
As U.S. vehicle recalls related to electronic systems have tripled and investigations quadrupled in the past 30 years after a surge in the use of computers to control functions such as acceleration, lawmakers and safety advocates say the National Highway Traffic Safety Administration has failed to keep pace with the technology. Complaints to NHTSA about vehicle electronic … [Read more...]
