Abstract
The fundamentals of electromagnetic field generation in wireless power transfer system are discussed, followed by explanation of the design of transmitting and receiving coils for electric vehicle application. Then, it presents the basic mechanism of magnetic field generation, the near- and far-field characteristics of the electromagnetic field, and the coil topologies for wireless power transfer system. Also, the coil structures of transmitter and receiver structure for OLEV application are discussed. To maximize the efficiency, the resonance frequency is carefully selected and the resonance circuit is constructed by using coil inductance and lumped capacitance. The use of the magnetic material for SMFIR design, the criteria for optimal selection of the operation frequency in OLEV system, and the role of skin effects are discussed.
