The paper proposes an approach for easy and fast modelling and optimization of power electronics structures. It focuses on the EMC filter design. To achieve this task for electrical drives, a full EMC modelling of the application is defined by combining time simulation (or measurements), FFT and system modelling in the frequency domain. A modular description in a user friendly environment allows describing...
For the calculation of the common mode (CM) ground current in voltage source - inverter fed induction machines a simplified (SHF) and a distributed (DHF) high-frequency equivalent circuit are compared. The SHF circuit needs measured parameters of the electric machines, but gives good results in comparison to the measured CM ground current. The DHF circuit predicts the CM currents purely from calculated...
This investigation focuses on setting up a discrete model of the coupling between a TEM field generated inside a TEM cell to a device under test for use in a circuit simulator. In first instance, different microstrips are used as device under test because of their well-defined characteristics. The resulting models of the TEM cell, the microstrips and the electric field coupling between them are explained...
