“…Among the prior integration schemes, DC-3, which is shown in Fig. 10, is seen to be the simplest one in terms of the References [13], [15], [24], [43], [13], [46]- [48], [28], [49], [64], [65] [67] [26], [68] - [25]- [38] [39]- [41] [50]- [59] [40]- [43] Typical vessel segment(s) prior described integration complexity. Due to the direct-online connection of the batteries, the required number of PCSs is the lowest and only the power from the fuel cells has to be controlled.…”

Transportation electrification is undergoing a significant transitioning towards the utilization of efficient and reliable energy sources and smart integration schemes, where this transitioning is continuously facing ever-tightening challenges in order to comply with the increased environmental regulations. Among the different means of transportation, the global maritime transport is responsible for 2-3% of global greenhouse gas (GHG) emissions and it is predicted to increase to 17% by 2050 if no changes are adapted. Hence, the international maritime organization (IMO) has targeted to reach a 50% reduction in GHG emissions by 2050 compared to 2008. Hence, alternative energy sources shall be utilized in order to meet these strict GHG emissions reduction targets, where batteries and hydrogen-fed fuel cells can play a vital role in such aspect. Since the output of these two energy sources is unregulated DC voltage, their connection to the whole ship power system can be accomplished in several ways, where each way has its features, in addition to utilizing different power conditioning stages (PCSs), and these features are not well clarified and compared in the literature. Hence, this paper presents an overview of the possible integration schemes that can be utilized in fuel cells and batteries-fed vessels, which is supported with a comparative assessment. This is also presented along with highlighting the state-of-the-art PCSs that are available in the market and can be utilized in these integration schemes within marine vessels. Such overview and comparative assessment are seen to be of significant importance and added value for researchers and developers in both the academic and industrial sides in order to accelerate the adoption of fuel cells in marine systems for zero emission shipping.

“…[1,2] Until now, a large number of SiC junction barrier Schottky (JBS) rectifiers have been reported for a wide range of applications. [3][4][5] The main advantages of the JBS rectifier are the Schottky-like on-state and the fast switching characteristics together with the offstate characteristics having a low leakage current similar to that of the PiN rectifier. To reach a breakdown voltage close to the ideal one, various junction termination techniques for the SiC devices have been developed, involving field plate (FP), [6] field limiting ring (FLR), [7] and single-and multiple-junction termination extensions (JTE).…”

Experimental and numerical analyses of high voltage 4H-SiC junction barrier Schottky rectifiers with linearly graded field limiting ring

This paper describes the successful fabrication of 4H-SiC junction barrier Schottky (JBS) rectifiers with a linearly graded field limiting ring (LG-FLR). Linearly variable ring spacings for the FLR termination are applied to improve the blocking voltage by reducing the peak surface electric field at the edge termination region, which acts like a variable lateral doping profile resulting in a gradual field distribution. The experimental results demonstrate a breakdown voltage of 5 kV at the reverse leakage current density of 2 mA/cm 2 (about 80% of the theoretical value). Detailed numerical simulations show that the proposed termination structure provides a uniform electric field profile compared to the conventional FLR termination, which is responsible for 45% improvement in the reverse blocking voltage despite a 3.7% longer total termination length.
