In Tokamak accelerators, the high-frequency switching-mode power supply (SMPS) causes electromagnetic interference that not only affects the public power system but also results in abnormal operation of other key equipment connected to the common ground terminal, such as the measurement and diagnosis system. In this article, to develop a model of the conducted interference of high-frequency SMPSs,...
Due to its working modes, the Switching Mode Power Supply (SMPS) has low electromagnetic compatibility with other systems, such as Langmuir probes used in ion-source accelerators for heating plasma. Its high-frequency Electromagnetic Interference (EMI) is analyzed for its bias power suppl y of its core snubber. Located in the same HV pole of the accelerator, the EMI of SMPS lets its Langmuir probes...
The core snubber is one of the most important devices in the EAST (Experimental Advanced Superconducting Tokamak) with NBI (Neutral Beam Injector) system. This device is designed to protect the NBI system during periods of high voltage breakdown. The theory for the core snubber was developed by Fink, Baker and Owen (the FBO model), who considered only resistance effects which generates a snubber design...
