摘要： A monorail vehicle includes a chassis supporting a vehicle body that includes a passenger floor, a first side wall, and a second side wall and first and second propulsion systems. Each propulsion system includes an electric motor and a drive wheel coupled to a rotor of the electric motor. Each electric motor and the drive wheel coupled to the rotor of the electric motor are positioned on both sides of an imaginary plane extension of the passenger floor. First and second shells cover portions of the first and second propulsion system. The first shell is positioned proximate to the first side wall and defines a first space between the second side wall. The second shell is positioned proximate to the second side wall and defines a second space between the first side wall.

摘要： A power converter for an electric locomotive includes an insulating transformer, an AC/DC converter, an inverter, a PWM controller, and a voltage controller. The insulating transformer is supplied with high-voltage AC power from an AC overhead wire to convert a high voltage to a low voltage and output low-voltage AC power. The AC/DC converter receives the low-voltage AC power and performs AC/DC conversion. The inverter receives an output from the AC/DC converter and performs DC/AC conversion for supply to a load. The PWM controller outputs a PWM control signal having a predetermined pattern, the pattern for removing specific harmonic components from an output of the inverter or attenuating the specific harmonic components to at most a predetermined level. The voltage controller controls a DC output voltage of the AC/DC converter to control an output voltage of the inverter.
