    Abstract —In this paper a new methodology for the prediction of the conducted-emission propagation in an in-house power- line network is presented. This methodology is based on the modal S -parameter characterization of the devices present in the power-line network, as well as on the modal modeling of branch- line connections. The modal S parameters relate common- and di ff erential-mode waves, and give more information regarding interference propagation. With this methodology, common- and di ff erential-mode attenuations, and modal conversion between common and di ff erential modes can be accurately predicted, which is of great interest for power-line communication devel- opment and conducted-emission mitigation. This methodology is tested by accurately predicting the interference levels up to 100 MHz of an in-house power-line network composed by thermal- magnetic circuit breakers, residual-current circuit breakers, single-phase wires and light bulbs.

    A complete system able to measure complex impedance, both in magnitude and phase, of an automotive electrical load is designed. The development of such system emerged from the need of measure the impedance of these loads in a wide range of frequencies (100 kHz to 30 MHz) while being connected to power supply and in operation. This powered up condition introduces several problems when the impedance is measured by means of traditional instruments such as Vector Network Analyzers (VNA), which could be damaged by transients. Understanding the behaviour of electrical cars loads in the frequency domain is of primary importance not only for in-vehicle Power Line Communication (PLC) channels response, but also to understand electromagnetic emissions (EMI)problems related with this type of communications.
