<p>PURPOSE:To improve comfortableness in triple feeder system by obtaining accelerating/decelerating force continuously even upon stoppage of one power converter. CONSTITUTION:A triple feeder power supply circuit arranged with thrust coils for linear synchronous motor is disposed on the ground side. A field coil 16 for a thrust coil 17 is mounted on a vehicle 15 and thrusts corresponding to sped patterns 2, 28 are operated. In a linear synchronous motor controller where a power converter 7 receives a current command corresponding to the thrust and a current phase and feeds power to the thrust coil 17, means 1 produces the speed patterns 2, 28 corresponding to two power converters 7 when one of three triple feeder power converters is stopped and thrust control of train is carried out through two power converters 7.</p> |
