Description

The superconducting magnetic levitation (maglev) system under development in Japan uses a linear synchronous motor (LSM) with armature coils on the ground. The power converter driving the LSM should be able to generate power of variable voltage and frequency according to the speed and thrust of the train. Therefore, we adopted a pulse width modulation (PWM) inverter on the Yamanashi Maglev Test Line. For power conversion the maglev system requires highly efficient large-scale PWM inverters. In addition, manufacturing costs had to be reduced, so we developed several control methods to enhance the output voltages of the inverter without changing its circuit configuration. This paper describes the characteristics and some results from experiments involving these control methods.
