INDUCTIVE POWER COUPLING FOR AN ELECTRIC HIGHWAY SYSTEM

A Dual Mode Electric Transportation (DMET) system is under development in which energy is electromagnetically transferred from a powered roadway to moving vehicles. Energy from the roadway can be used for high-speed, long-range travel and for replenishing energy stored in the vehicle in batteries or flywheels. The stored energy is then available for short-range travel off the powered highway network. The power coupling between roadway and vehicle is functionally similar to a transformer. A source is embedded in the roadway flush with the surface. When the vehicle's pickup is suspended over the source, energy is magnetically coupled through the clearance air gap between pickup and roadway source. The electromagnetic coupling mechanism was extensively studied through computer models, circuit analyses, and by tests of a full-size physical prototype. The results of these tests are described.
