High voltage, high current power supplies are required to generate plasma in a tokamak. This equipment converts high voltage AC from the grid into both AC and DC energy sources. Recently, new switching devices based on wide bandgap semiconductors have emerged that could significantly improve the efficiency of these systems. This paper explores the benefits of using silicon carbide (SiC) MOSFET power...
EAST (Experimental Advanced Superconducting Tokamak) fast control power supply is a large capacity single phase inverter power supply, which traces displacement signal of plasma, and excites four fast-control coils in vacuum chamber to produce magnetic field that realizes plasma stabilization in large elongate model. To meet the requirement of large current and fast response, multi-inverters in parallel...
