Description
Summary:This paper is devoted to the experimental validation of the 3D modeling approach for studying the shielding properties of high voltage (HV) connectors used in electric and hybrid vehicles with an arbitrary number, shape, size and location of apertures. The 3D simulation model is based on the method of moments (MoM), and novelty is in special implementation of Mitzner surface impedance boundary conditions (SIBC) for nested regions bounded by thin material sheets with apertures. This implementation implies the so-called null-field approach. Both measured and simulated results for the transfer impedance of prototype models of the HV connectors are presented and compared for various numbers and shapes of apertures.
