International audienceThe reduced switching times of silicon carbide (SiC) components compared to Si components in similar conditions are a great advantage from the point of view of efficiency, but, due to the high dv/dt and di/dt, conducted electromagnetic emissions are increased. Therefore, the availability of a method which can predict these emissions is increasingly necessary. To the best of the authors' knowledge, a model that can predict differential mode as well as common mode for a converter including sic devices has not yet been published. the novelty of the work presented here is the integration of different modeling approaches to form a circuit model of a SiC-based buck dc-dc converter working in frequency range from 40 Hz to 30 MHz. A modeling approach of the passive parts of the converter is presented. Then, the model obtained is used in simulations to predict the drain-to-source voltage and the drain current for the JFET. Conducted emissions received by the line impedance stabilization network are also computed. Simulation results are compared to measurements for different duty cycles and different gate resistors in the time and frequency domains. A good agreement is obtained. In the frequency domain, in all cases, differences are less than 5 dBμV up to 30 MHz excepted in the JFET source current

“…For example, with the change of frequency from 100 kHz to 250 kHz, a SiC JFET/JBS power converter efficiency shows only a weak change, in contrast to the drop from 95% to 92.5% when using a Si CoolMOS and SiC JBS combination [40]. Increasing the switching frequency is advantageous from the point of view of inductive and capacitive circuit components which can be smaller, cheaper and introduce less power loss.…”

The success of electric vehicle drives heavily depends on the maximization of energy conversion efficiency. Losses in power electronic converters increase system size, weight and cost, raise energy demand and limit the operating distance range. Advances in semiconductor technology can remedy these problems and silicon carbide devices are of special interest in this context. This material enables manufacturing high-voltage devices with lower on-state voltage drop and shorter switching times, thus reducing both static and dynamic power loss. In this paper, recent achievements in silicon carbide technology as well as their applications in electrical vehicles have been reviewed.

“…Their particular connection defines the topology. The development of new topologies for the PSs has been evolved in parallel to the advancements in the technology of materials and devices [4] as well as in the theory of the control systems [5], [6]. According to the operating mode, there are three basic PS types: 1) linear, 2) switching-mode, and 3) soft-switching or resonant.…”

The paper deals with the use of resonant converters for the power supply of electric equipment. After exploring the advantages of using the resonant conversion, an analysis of the three main resonant topologies, namely i) series-resonant, ii) parallel-resonant, and iii) a combination of them, is carried out and a series resonant converter is implemented. Considerations on the design of the resonant converter as well as on the selection of their components, including the HF transformer, are presented. Performance of the implemented series resonant converter is investigated in terms of dynamic behavior through experimental results.
