In his video published by Omicron Lab, Arturo Mediano – University of Zaragoza studies impact of inductor resonance to its performance and how it impacts EMI Electromagnetic Interference.
Inductors are one of the essential components in the design of any electronic system, alongside capacitors.
They come in various types, including air-core and magnetic-core inductors, and are utilized in low-signal applications as well as in power electronics. Inductors play critical roles in the design of filters, impedance matching networks, DC/DC converters, oscillators, and more.
However, inductors are not ideal components. Their resonant frequencies can pose significant challenges, particularly in the context of Electromagnetic Compatibility (EMC) and EMI design. These resonances can lead to unintended oscillations or issues, which are often complex and challenging to diagnose.
In this video, we will introduce the nature of these resonant frequencies, exploring how they can be measured and modeled in a basic form. We will also present some examples such as buck converter illustrating the critical problems that arise when attempting to achieve designs compliant with EMC standards. Understanding these resonances is vital for developing robust electronic systems that minimize interference and optimize performance.
