“…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.…”

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.

“…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.…”

“…First, the simulations of conventional PWM technique and chaotic switching are done. Then the hardware prototype of passive filter [7] is designed for EMI filtering and later added to the chaotically switched DC-DC converter in which the hard ware prototype is driven by pulses generated using the costeffective FPGA.…”

A new and simple but effective electromagnetic interference suppression technique based on field programmable logic array (FPGA) technology to provide a significant EMI noise attenuation in DC-DC converters is discussed. The voltage controlled boost converter for EMI reduction is analyzed using FFT under traditional PWM technique and chaotic mode operation. This technique aids the DC-DC converters to comply in specified EMI limits and replace conventional bulky passive filter with a simple passive filter. A prototype model has been tested and hardware results show significant reduction of EMI in chaotic mode operation of the boost converter.

The paper deals with the designing, realization and testing of a network filter used to reduce the electromagnetic disturbances produced by static switching equipment. The tests were done according to the CISPR 17 standard for the determination of the insertion loss for each cell, and the verifications concerning the filter's efficiency with respect to the conducted and radiated disturbances produced by a static switching equipment revealed the obeying of the CISPR 11 standard. One presents the experimental determinations made previous to network filter use. After the filter's designing and realization, experimental data relative to the conducted emissions were gathered. The assembling and case shielding were improved in order to obey the limits imposed to the radiated emissions according to the CISPR 11 standards, and consequent experimental determinations revealed significant improvements from the EMI point of view.
