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...]
Extending the Concept of Common Mode Noise: Single Mode
Electronic switching circuits are used for power conversion, data communication and other applications. According to the theory of Fourier Transform, in these circuits, the periodical change of the current/voltage produces harmonics in a wide frequency spectrum. The resultant currents of these harmonics are called conducted emission (CE), and are categorized classically as … [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...]
