基于15kV SiC IGBT的固态变压器固态变压器不仅是变压器,而且是故障电流限制器、无功功率补偿器和电压暂降恢复器。这些优点使固态变压器在未来电力电子领域具有广泛的应用前景。图8给出了提出的用于FREEDM系统的单相10kVA固态变压器的基准拓扑。它包括了功率变换的三个环节。第一环节为AC/DC整流器,将7kV的单相交流电转换为10kV直流电。第二环节为 Solid state transformers based on 15kV SiC IGBTs Solid state transformers are not only transformers, but also fault current limiters, reactive power compensators and voltage sags regulators. These advantages make the solid state transformer in the field of future power electronics has a wide range of applications. Figure 8 shows the proposed benchmark topology for a single-phase 10kVA solid state transformer for a FREEDM system. It includes the three aspects of power conversion. The first link is an AC / DC rectifier that converts 7kV single-phase AC to 10kV DC. The second part is
