Switching transient induced skin effect in Packet Energy Transfer systems

In this article, the electromagnetic analysis of skin effect during switching transients and faults in transmission cables used in Packet Energy Transfer (PET) systems is in-vestigated. The study covers the electromagnetic diffusion of current density during switching transients in high frequency switched-mode power supplies (SMPS). The mathematical model for such electromagnetic phenomena are discussed and simulation models are developed to illustrate the transition process. The radial current density distribution inside conductor is studied and time domain analysis of the cable resistance and power loss is analyzed. The dynamics of temporal change in total current and effective resistance that account for the power loss during switching transients are also discussed.
