DRIFT PREVENTION DEVICE IN SUPERCONDUCTING PARALLEL CIRCUIT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a drift prevention device which reduces a power loss rather than a conventional current regulator and is small-sized and lightweight.SOLUTION: The drift prevention device supplies a current to a superconducting parallel circuit device comprised of a plurality of superconducting coils connected in parallel and prevents a drift between the superconducting coils. The drift prevention device comprises a plurality of inverters which are provided for each of the superconducting coils and supplies electrification currents to the superconducting coils. The plurality of inverters synchronously generate electrification currents so as not to generate the drift between the superconducting coils forming the same phase based on preset current distribution information.SELECTED DRAWING: Figure 2
