Method and Device for Power Supply to an Electric Motor Vehicle

摘要

Method of producing a plasma conductor in air with the aid of a femtosecond high-frequency pulsing and high-repetition rate laser. The plasma is used for transmitting a current between an electric or catenary wire supplying a vehicle such as a train and an electric contact, for example a pantograph arm disposed on a moving vehicle and connected to a power distribution system thereof. The plasma is in contact with the electric or catenary wire and with an electric contact.
