Power electronics professionals are often highly interested in the fundamentals of EMI, as they frequently encounter (or suffer from) its effects in their labs (EMI and RF black magic) or in production environments (EMC). Many of them face the need to solve these problems quickly, under pressure, and often through trial and error. In this process, near-field probes are invaluable tools. The key concepts and practical examples presented in this seminar will be highly beneficial for engineers and technicians who may not be EMI/EMC specialists but are involved in the design, manufacturing, and troubleshooting of power electronic products. Topics such as identifying EMI sources, evaluating fixes, testing components, PCB layout, shielding of cables and enclosures, and non-invasive signal measurement will be covered from an experimental perspective. Taking this seminar provides an opportunity to review EMI/EMC and high frequency concepts relevant to power electronics and to learn, through a practical approach, how to use near-field probes to solve design issues and noncompliance in power electronic systems. The seminar will be presented with the following considerations: - Attendees are power electronics professionals who are typically very interested in lab work and EMI/RF experimentation, though they are usually not EMI/EMC or RF specialists. - Practical, real-world examples are generally well received, so they will be incorporated into the presentation. - The tutorial will avoid complex mathematical treatments of EMI/RF, focusing instead on a practical perspective for more effective learning outcomes.
