摘要：

Inductive wireless power transfer technology (WPT) is gaining momentum recently for wide range of applications. This ranges from charging of portable electronic devices to static and dynamic charging of electric vehicles. It is enabled by the use of magnetic coils wound in certain shapes and dimensions. In order to gain optimal wireless power transfer, coil parameters such as the wire spacing and the core area, are critical. A less optimal selection of values for these parameters can lead to destructive or constructive interaction between the generated fields. In this letter, some coil parameters such as the inter-layer and turn spacing of the Layered DD (LDD) coil are investigated to determine how they influence the inductance which influences the WPT efficiency. It was deduced that the start radius of the LDD coil is directly proportional to the inductance. The inter-layer distance and change in radius exhibit an inversely proportional relationship.
