Abstract
The overall system architecture of wireless power transfer system for electric bus is presented. The inverter system converting 60 Hz power source into 20 kHz power source supplies 20 kHz current to the power cable module embedded under road. Many litz wire cables are used to eliminate skin effects in generating magnetic flux. The pickup module is attached at the bottom of bus to collect the magnetic flux. At magnetic resonance, induced electric power is delivered through regulator to motor or battery system. Using ferrite core structures such as EE type or UU type, magnetic flux is channeled to increase the power transfer efficiency as well as satisfy the EMF requirement. The power transfer process between the power cable module and the pickup module consists of four phases, i.e., selection, ping, identification, and configuration.
