High Speed Rail (HSR) are expanding rapidly in the whole world in this decade. Almost all the high-speed trains are fed by high-voltage and are equipped with several large motors. In addition, High-speed trains have a strict restriction for both mass and size. Thus, HSR needs power semiconductors that can handle high-voltage and giant current. In addition, EMC problems become larger in these days,...
The characteristics and losses of 10-kV SiC MOSFETs, p-IGBTs and emitter turn-off thyristors (ETOs) were compared using the experimental measurements, PSPICE simulations and numerical simulations. Using the extracted loss information and method of loss calculation in the AC/DC rectifier and DC/DC converter, the frequency capability of these 10-kV SiC power devices in a 20 kVA solid-state transformer...
