THREE PHASE ENERGY TRANSFER CIRCUIT WITH SUPERCONDUCTING ENERGY STORAGE COILS. Academic Article uri icon

abstract

  • The efficient transfer of energy between two superconducting coils can be achieved by commutating capacitors with thyristor networks. The inductor-converter bridge (ICB) is one of the circuits which allows controllable, reversible, and efficient transfer of the energy. The ICB circuit allows energy from one coil, in the form of direct current, to be transferred to capacitors to generate multiphase symmetrical voltages. These voltages are rectified to provide a time-averaged value of direct voltage needed to charge the second coil. Large superconducting coil systems requiring reversible and controllable transfer of energy between the coils are likely to have application in future tokamak fusion wer reactors and large particle accelerator systems. The pulsed power loads for the coils of these future systems have the prospect of exceeding 1000 Mw for periods of 1 to 20 s. A companion superconducting energy storage coil and thyristor network provides isolation of these massive pulsed loads from the utility grid.
