摘要：

Switching of semiconductor devices is the main source of electromagnetic interference (EMI) in power static converters. Fast power devices, in particular, generate high levels of emissions in the form of high-frequency currents known as common mode (CM) and differential mode (DM) currents. In power systems, these high-frequency disturbances travel and spread over the power cables. To study the influence of the power cable characteristics on the level of the conducted emissions, it is necessary to construct a precise model of the power cables, taking into account various phenomena that appear when the frequency increases. This paper deals with two-wire unshielded and shielded energy cables. It uses a distributed parameter model that takes into account the skin and proximity effects, and the dielectric losses. The model is simulated and validated (with LT Spice/SwitcherCADIII software) in the frequency and time domains.
