Title:
DYNAMIC POWER TRANSFER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/235256
Kind Code:
A1
Abstract:
This dynamic power transfer system (100) is provided with: a power transmission section (SC) having a segment group in which a plurality of segments (SG) each having an inverter circuit (32), a filter circuit (34), a resonant circuit (36), and a power transmission coil (40) are connected to a moving body along a traveling direction in parallel with each other; a power supply circuit (10) for supplying power to the segments; and a control unit (16) for controlling the operations of the segments. The control unit sets one of the plurality of segments included in the power transmission section as a power transmission segment (SGm) and the other segments as non-power-transmission segments (SGs), generates a magnetic field in the power transmission coil of the power transmission segment by supplying power to the power transmission segment, and uses electrical characteristics that are current and voltage which are generated in the non-power-transmission segment due to magnetic coupling with the magnetic field and another electrical characteristics that are the current and voltage of the power transmission segment to detect the presence or absence of an abnormality of the power transmission segment and the non-power-transmission segment.
