Abstract

Abstract The planar spiral square coil (PSC) is one of the most common structures used in wireless power transfer (WPT) applications. In this paper, a new self-inductance calculation method is proposed for PSC. The self-inductance of the coil should be calculable in order to comprehend the interaction between the coil and the WPT system. In this paper, A new self-inductance calculation method for PSC is proposed by using Greenhouse's method of calculating the inductance between the conductors. The proposed new greenhouse method has been tested for various square sizes, spaces between conductors, the number of turns, and conductor widths. Also, the proposed new method was compared with Current sheet method, modified Wheeler method, and Ansys Maxwell 3D simulation results in terms of calculation error rate. The self-inductance calculation error rate of this method was lower than in all other studies and was below 0.4% in all cases.
