  • Systematic Analysis of Induction Coil Failures. Part 13: Electromagnetic Proximity Effect (.pdf)
    Authors: Valery Rudnev. Publication: Heat Treating Progress, Professor Induction Series. Date: 10/1/2008. This article is one of series of articles devoted to a systematic scientific/engineering analysis of failures of induction heating coils and prevention. Electromagnetic proximity effect has

The current-signal domain is relatively immune to EMI, and, compared to voltage. signals, current signals can run
