Results from a Model System of Superconducting Solenoids and Phase-Shifting Bridge for Pulsed Power Studies for Proposed Tokamak EF Coils

Abstract

Superconducting energy storage inductors have been proposed [¹] for storing the energy of the OH and EF coils of tokamak power reactors between plasma burn cycles. Because the EF coils of a tokamak must be excited dynamically in response to plasma current, temperature, and position during the burn cycle of the reactor, unique requirements are made of the EF coil power supply system. An energy transfer circuit suggested by Peterson et al. [²] promises to meet the power transfer and control requirements of the EF coil excitation circuit supplied from a storage inductor.
