SHUNT PROTECTION FOR SUPERCONDUCTING MAGLEV MAGNETS
Abstract Closely coupled, short-circuited shunt coils are proposed for quench protection of super-conducting Maglev magnets which use high resistance, matrix composite conductors. It is shown that, by suitable design, the shunts can reduce ac losses and that the changing currents during magnet energization or vehicle lift off and landing can be tolerated.
High‐efficiency flux pump power supply using inductive current transfer
A superconducting flux pump power supply of the transformer–rectifier type is described. Load current commutation between gates is by transformer primary current control. A simple, inexpensive system of generating the required control waveforms is outlined. Results of load magnet charging tests to currents of 500 A are given and are consistent with calculated performance.
