ECE 5234 - EMI and Noise Reduction Techniques and Filter Design (3C)

Theory and practice of electromagnetic interference (EMI) noise coupling; techniques for noise reduction: shielding, grounding and filtering. Limitations of circuit theory, parasitics in circuits and their physical origins, measurement of EMI to comply with government regulation. EMI problems and solutions to switching power supply applications. Design of EMI filter, magnetics design, eddy currents.

Electromagnetic interference requirements and means for meeting these requirements have become a critical aspect of circuit design. EMC regulations worldwide have become increasingly stringent and will continue to do so. this material is essential for students intending to specialize in practical circuit design. Since the course teaches practical methods to bridge the gap between circuit theory and the physical world as it applies to EMI/EMC using electromagnetics theory, it is a much needed course in our degree program and is extremely popular among the students in the power electronics and pulse power areas, among others, where they are dealing with EMI in projects involving practical circuits.
