A System for Dynamic Inductive Power Supply of Electric Vehicles on the Road

A Moving Field Inductive Power Transfer (MFIPT) system for wireless inductive power supply of electric vehicles while driving will be described. The MFIPT system for supplying power to electric vehicles while driving along the route uses primary coils arranged below the pavement. These primary coils transmit the energy via an alternating magnetic field to a secondary coil located at the vehicle below its floor. Only those primary coils located below the secondary coil of a vehicle are excited. By this way losses and radiation in the environment are minimized. The operation principle of the MFIPT system is based on a switched DC to DC converter which converts the DC power supplied by the stationary power line to DC power delivered to the moving electric vehicle. The dynamics, the operating regimes and the power balance of the MFIPT system and the costs for the implementation of the system are discussed.     «
