Resistor Insertion in crowbar circuit of the Pulse Power System for Korean ETC Accelerator

전열화학추진장치용(電熱化學推進裝置用) 대전류(大電流) 펄스성형(成形) 회로의 크로우바 저항삽입의 검토

The high current pulsed power systems(PPS) for rail guns, ET and ETC accelerators require many components of very high cost. If one failed to select component specifications based on optimal design, cost effective and reliable PPS could not be obtained. It is very significant to study a preliminary circuit scheme and to determine optimal specifications via circuit simulation before constructing the PPS based on modulized capacitor banks. The optimal crowbar resistor value, module inductance was determined in view of energy loss, the voltage reversal of capacitors and the transient current of crowbar diodes.
