  • Patent number: 10141858
    Abstract: 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.

  • Patent number: 10106043
    Abstract: The invention relates to a charging device for an electric vehicle that can be driven by an electrical energy store. The charging device has a charging interface outside the electric vehicle, which can be fed by a three-phase alternating current from an external three-phase alternating current network. The charging device provides a charging current at the output that can be fed via a charging cable to the electric vehicle in order to charge the electrical energy store. The charging interface comprises a converter device configured to convert the three-phase alternating current into a single-phase alternating current as the charging current, and to distribute a phase load on the conduction phase of the single-phase alternating current substantially uniformly onto the three conduction phases of the three-phase alternating current during operation.
