Abstract: PURPOSE: A magnetic levitation system by a permanent current mode operation type superconducting hybrid electromagnet for a magnetic levitation train is provided to prevent the performance deterioration of the magnetic levitation system due to a demagnetization phenomenon. CONSTITUTION: An iron core(100) is formed by laminating a plurality of U-shaped iron plates. A conductive coil(200) is wound around both ends of the iron core. A superconducting coil(300) includes a PCS switch unit(500) and a current leading line. The superconductive coil generates magnetomotive force of an electromagnet to obtain the levitation force of a magnetic levitation train. The superconducting coil is wound in a cryostat. A charging switch(600) is installed outside the cryostat. A power converter(700) is comprised of a DC chopper circuit which is comprised of a power converting device like SMPS. A control unit(800) controls a microcomputer. A levitation gap sensor unit(900) detects magnetic field due to levitation gap between the magnetic levitation train and the superconducting hybrid electromagnet.

Abstract: PURPOSE: An inverter control apparatus is provided to be capable of controlling an abnormal voltage increase of a DC link stage owing to an overcurrent probability at an acceleration and regeneration at a deceleration. CONSTITUTION: An overcurrent interrupt generating part outputs a fault signal with respect to an overcurrent so that a processor part processes an interrupt operation when a current over a limited value is detected. The overcurrent interrupt generating part constructs a signal differently input from a current detecting part via a three-phase full-wave rectifier. A voltage detecting and overcurrent interrupt generating part detects a current voltage so that the processor part copes with an overvoltage and generates an interrupt signal with respect to the overvoltage.
