Analysis and Design of the Iron Core as the Arc Snubber. in the EAST NBI System

A special winding iron-core is designed to act as the snubber for the neutral beam injection （NBI） power supply （PS） system in EAST, which will limit the fault current and energy caused by occasional sparking in the NBI ion source. 50-50 Ni-Fe is chosen as the high-frequency magnetization material f...

Summary:A special winding iron-core is designed to act as the snubber for the neutral beam injection （NBI） power supply （PS） system in EAST, which will limit the fault current and energy caused by occasional sparking in the NBI ion source. 50-50 Ni-Fe is chosen as the high-frequency magnetization material for the iron-core. Equations for the snubber is derived from the design of the iron-core. The iron-loss factor and eddy-current losses are found to increase in a sample experiment at a frequency from 1 kHz to 20 kHz. A 1：10 miniature of the iron-core is tested and performs well with a fine capability.
