Voltage Ripple Reduction Control of Energy Transfer Circuit with Inductor Converter Bridges Between Superconducting Magnets

Abstract

Energy transfer circuits between two superconducting magnets have been proposed, discussed and tested. We have studied on power supplies for superconducting magnets which consists of a small power converter, a superconducting magnet for an energy storage, and an energy transfer circuit of inductor converter bridges (ICB). We derived analytical solutions on the basic characteristics of ICB energy transfer circuits. In this paper, from the analytical solutions, a new control method of ICB trasnsfer circuit to reduce voltage ripples across a load superconducting magnet is proposed and discussed. Availabilities of the proposed control method are confirmed by the computer simulations.
