“…The second alternative would be the amorphous material which is not suitable for the high-power applications. Moreover, it was shown that the power loss for core material could be optimized by regulating the frequency range [86].…”

“…Accordingly, Litz wire is chosen to reduce the impact of skin effect by subdividing the conductor to smaller conductor strands with proper shields [91]. Several hundreds of tiny strands are insulated from the others and form a thicker wire with the thickness equal to the wire size which is then calculated in volt power calculations [86]. It is important to know that the thinning of the wire strands would result in a better performance in HF characteristics.…”

Solid-state transformer (SST) is an emerging technology integrating with a transformer power electronics converters and control circuitry. This paper comprehensively reviews the SST topologies suitable for different voltage levels and with varied stages, their control operation, and different trends in applications. The paper discusses various SST configurations with their design and characteristics to convert the input to output under unipolar and bipolar operation. A comparison between the topologies, control operation and applications are included. Different control models and schemes are explained. Potential benefits of SST in many applications in terms of controllability and the synergy of AC and DC systems are highlighted to appreciate the importance of SST technologies. This review highlights many factors including existing issues and challenges and provides recommendations for the improvement of future SST configuration and development.

“…Multi-winding medium frequency transformer (MMFT) [6][7][8][9], responsible for voltage transformation and potential isolation, is the core component of M-PET. Compared with the scheme of using several single-input single-output medium frequency transformers (MFT) [10][11][12][13][14][15][16][17] to achieve multi-input and multi-output, the MMFT scheme can reduce the number of transformer and the number of voltage conversion, therefore, the system structure can be simplified, volume and weight can be reduced, and lower cost can be achieved.…”

“…Besides, the number of conductors increases rapidly due to the increase of winding number, which poses a challenge to the modeling of MMFT since a large amount of computing resources and time will be consumed as the complexity of model increases. Previous work on MMFT can be found in [6][7][8][9]. Ref.…”

The multi-winding medium frequency transformer (MMFT) has attracted widespread attention, since its application in power electronic transformers can simplify the system structure and reduce the volume and weight. However, the special working conditions of MMFT due to high voltage and high power density increase the difficulty of insulation design for MMFT. For this issue, this paper presents a comprehensive analysis of electric filed characteristics for MMFT. First, the electric field model of MMFT is established using the 2-D finite element method. Based on it, the influences of connection mode, core structure, and hollow winding on the electric field characteristics of MMFT are studied, including the overall electric field distribution, maximum electric field intensity, and the electric field intensity along a fixed path. The results show that there are differences in the maximum electric field intensity for different connection modes and different core structures, which provides references for MMFT insulation design. The proposed modeling method and analysis results in this paper are important for insulation improvement of MMFT.
