  • Patent number: 11381192
    Abstract: Provided is a power conversion controller in which variation in reactive power among power conversion controllers can be inhibited while maintaining the running performance of vehicles. The power conversion controller includes a power factor setter that sets a power factor based on a detection value of an overhead line voltage, and a calculator that calculates a reactive current command value by multiplying an active current command value by a tangent of a power factor angle of the power factor. The power factor setter sets a reference value set in advance as the power factor if the detection value is within a reference range, sets a value smaller than the reference value as the power factor if the detection value is below the reference range, and sets a value larger than the reference value as the power factor if the detection value is beyond the reference range.

  • Patent number: 10842359
    Abstract: Sensing parts are formed in different directions in a circumferential direction in substantially a same position in the longitudinal direction thereof. Each sensing part is configured to include an optical characteristic changing member which generates the optical signals having absorption wavelength characteristic regions that vary from sensing part to sensing part by giving an optical characteristic change, which differs from that of other sensing parts, to the sensor light incident thereon in accordance with an amount of bending in a specific direction. A light detector detects the optical signals included in sensor light from a light source, which has passed through the sensing parts and undergone the optical characteristic change.
