High Frequency Behavior of Electrical Components

This course covers the high-frequency behavior of various electrical components such as conductors, capacitors, inductors, resistors, mechanical switches, and transformers. For instance, it delves into the concept of skin effect in conductors, which states that the current density across a conductor is not uniform under high frequencies. It also explores the impact of frequency on the behavior of these components and discusses concepts like internal and external inductances, self and mutual inductances, and loop and partial inductances. The course further explains the behavior of ideal and real capacitors, inductors, and resistors under different frequencies, and the concept of parasitic elements. Additionally, it provides practical tips on selecting and using these components effectively in high-frequency environments. Lastly, it discusses the characteristics of small transformers, the dynamics of switch operation, and noise suppression techniques. This course has been developed by Prof. Daniel Mansson and Prof. Rajeev Thottappillil from KTH Royal Institute of Technology, Sweden for NPTEL.
