Developed in Japan with a superconducting magnetic levitation system uses ground linear synchronous motor armature coil (LSM). The power converter can be provided according to train speed and traction power supply voltage and variable frequency. So for the Yamanashi Maglev Test Line has developed a pulse-width modulation (PWM) inverter. In addition, to reduce manufacturing costs, has developed several control methods, without changing the configuration of the inverter circuit can increase its output under voltage. The authors describe the characteristics of these control methods and some test results.

0 Introduction of Japan's superconducting maglev system developed using superconducting magnets and ground with the vehicle's linear synchronous motor armature coil (LSM). Linear synchronous motor drive converters with power can provide according to train speed and traction power supply voltage and variable frequency. Therefore, the Yamanashi Maglev test line using the pulse-width modulation (PWM) inverter. Drive high-speed trains require large inverter system, the capacity of .
