“…The CE causes significant electrical damages and communication malfunctions in many systems [17][18][19][20][21][22][23][24]. To reduce the CE, there are several methods [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] with different signal attenuation patterns. Each electrical system has different CE characteristics, so the CE attenuation method must be appropriately chosen for each system.…”

Road lighting systems require a significant amount of electric energy. To compensate for the utilized energy, the concept of a nanogrid road lighting system is presented. A solar panel is installed on the top of a lighting pole to generate electric power. In this research, a photovoltaic simulator (PV simulator), which is used to simulate solar behavior such as current, voltage, and power based on temperature and solar irradiance levels, is employed to replace a solar panel. In the nanogrid system, grid-connected and stand-alone micro-inverters are employed to convert the electric power. The inverters comprise switching devices that can generate electromagnetic interference (EMI) when operating, which is harmful to the grid system and the electrical equipment. In general, EMI has been studied and reduced in electrical appliances, which only receive electric power. However, for the nanogrid system, which supplies electricity to the grid system, there is less study on the EMI topic because the usage is still not widespread. In the future, the nanogrid system will be widely used delivering high power directly into the electrical grid system. Therefore, the study and attenuation of EMI in the nanogrid system are very promising. Conducted emission (CE) is one form of EMI that flows through a cable connecting several appliances in the frequency range of 150 kHz to 30 MHz. CE of grid-connected and stand-alone micro-inverters have high levels in the low-frequency range between 150 kHz–5 MHz and then decreases steadily. CE attenuation is important for this inverter in a solar power system. This research studies the effect of CE mitigation on the nanogrid system. The result is compared with the Comité International Spécial des Perturbations Radio (CISPR) 14-1 standard. Finally, the passive EMI filter can reduce CE and meets the CISPR 14-1 standard.

“…Therefore, the capacitance C isn't dependent on temperature. The capacitance C can also be calculated for frequencies above the first resonant frequency (f > F 1 ) using the expression defined in (5), because at high frequencies, the inductive effect is negligible compared to the capacitive one and the modulus impedance is also independent of temperature. 1 2 .…”

“…Inspired from the methods used and the models developed in [4], [5] and [6] to design and model coupled inductors and EMI filters, a high frequency model including the thermal dependence is proposed in this paper. Simulations are compared to measurement results from real prototypes in order to test their effectiveness and reliability with regard to temperature variations.…”

Coupled Inductors are widely used in EMI power filters. The impact of temperature on the frequency behavior of these components is very significant and shouldn't be neglected. In this paper, characterization test-benches and modeling methods of coupled-inductor impedances via measurements are presented for two types of magnetic cores: nanocrystalline alloy and Manganese-Zinc (Mn-Zn) ferrite. The aim of this study is to propose relatively simple models in order to estimate the thermal behavior of these components by simulation, for frequencies ranging from 10 kHz up to 100 MHz and temperatures ranging from -40°C up to 200°C. The new model is simulated and the obtained results are compared to the experimental measurements in the frequency domain. The developed model is then translated to VHDL-AMS language for easy implementation in most electrical simulation softwares.

“…The main solution used to reduce these conducted emissions consists to use passive filters made from the inductors and capacitors [8][9][10]. The properties of magnetic materials used in the inductors have a great influence on the performances of the filter [11]- [12]. Many studies have highlighted couplings between the passive components and the tracks, which can reduce its effectiveness.…”

“…However, the simulation requires a more accuracy models of EMI filter components. Different high frequency models including the parasitic elements are proposed in literature [10][11][12]. In this paper, a high frequency model of the EMI filter which takes into account the common mode paths impedance is proposed.…”

This paper deals the design method of EMI filter associated with buck converter using silicon carbide (SiC) power semi-conductors. It's well known that to comply with EMC standards, EMI filters are necessary. The aim is to propose a design method based on an equivalent electrical circuit. Thus, the first step is the identification of the different elements of the proposed model but also the limits values of the parasitic elements of the passive components which play a major influence on the efficiency of the filters. The main objective is to study the influence of the common mode paths on the design of the filter before and after its installation. A filtering solution is proposed to reduce the high frequency disturbances caused by the fast SiC components. The simulation results obtained with the proposed model are compared with the measurements show the effectiveness of the proposed EMI filter design method.
