“…Their utilization allows higher switching frequency, however attention should be paid to the gate driver design and minimization of parasitic elements of the power circuit [33]- [35]. As modern SiC MOSFETs have proved their performance in high-voltage applications [36]- [40], they can be used in the synchronized VDR on the high voltage side. An appropriate selection of new wide-bandgap semiconductors and analysis of the benefits achieved along with economic concerns require additional research and development of new design guidelines.…”

“…Its operation in the range from 40 V to 400 V is described in [3], where efficiency higher than 90% was achieved for the 1:4 input voltage range from 100 V to 400 V at the maximum input current. High efficiency at the switching frequency of 100 kHz was assured by the SiC devices, which are essential to realize the high-frequency high-voltage IS converters [40]. The coupled inductor topology has used nearly the same inductance in the qZS network (1 mH) as the transformer based counterpart, while the input current ripple was higher due to the different operating principle.…”

Impedance-source converters, an emerging technology in electric energy conversion, overcome limitations of conventional solutions by use of specific impedance-source networks. Focus in this paper is on the topologies of galvanically isolated impedance-source DC-DC converters. These converters are particularly appropriate for distributed generation systems with renewable or alternative energy sources which require input voltage and load regulation in a wide range. We review here the basic topologies for researchers and engineers and classify all the topologies of the impedance-source galvanically isolated DC-DC converters according to the element that transfers energy from the input to the output: a transformer, a coupled inductor, or their combination. This classification reveals advantages and disadvantages as well as a wide space for further research. The paper also outlines the most promising research directions in this field.

“…In [10],designed a push-pull DC/DC converter achieved 93% peak efficiency developed for the HF isolation stage for a 1.3kW and operating frequency of 100kHz for PMSG-based wind turbines. However, no study has yet demonstrated the benefits of utilizing SiC in 2L-FB grid-side inverter based on 1200V SiC-MOSFETs module to improve the efficiency and achieve higher switching frequencies and power densities due to reducing the sizes of the passive elements and heatsink, neither optimized the heatsink design based on the wind speed distribution profile (i.e., in most works, the heatsink is designed based on the maximum operating output power).…”

“…However, few work has been done on the impact of SiC technology in small-scale wind energy. In [6], designed qZS-derived push-pull DC/DC converter in the boost stage of small-scale wind conversion system based on SiC MOSFETs, higher efficiency at high switching frequency is achieved. Our recent work, [7], reported the improvements that could be brought by SiC MOSFETs in small-Scale wind energy conversion system, the 2L-FB grid inverter presented higher efficiency especially at partial loads in the area of high wind speed distribution.…”

Power converters used in renewable energy conversion have to deal with intermittent and variable power availability from the source, which implies that they actually work at their maximum rated power for only a small fraction of their operational time. Still, traditional thermal management design of power modules has to refer to maximum load conditions. SiC-MOSFETs exhibit a very stable performance over a broad temperature range [1-3]; this feature enables to design the cooling device for nominal operational conditions, typically corresponding to a much lower than maximum power rating. When this capability is added to the decrease in the size of passive filter elements, which can be gained by the higher switching frequency capability of SiC MOSFETs, the result is a significant increase of the converter powe, density.
