چکیده
The coil design of the inductive power transfer (IPT) for a transmitter (Tx) and receiver (Rx) is crucial to determine performance IPT. Considering core loss copper Tx Rx coils, which are major terms whole IPT system, determination winding turns coils becomes key factor maximum coils. In this paper, an optimal laptop wireless charging applications with efficiency proposed. Under specific requirement IPT, N1,op N2,op can be determined by proposed procedure finite-element-method (FEM) based simulation analysis. From results methodology, efficiency, input DC voltage V dc target load found procedure. 40W prototypes two symmetry asymmetry were fabricated, verified experiments. To separately verify resistance model Steinmetz equation-based methods comparatively evaluated, it was that they matched well at temperature condition below 40oC. showed total weight thickness as efficiencies 95.1% 96.8% cases obtained procedure, practical solution design.

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Implementation of Identical Spiral Square Inductive Coils for Wireless EV Battery Charging Application
In recent years, the popularity of wireless inductive power transfer (WIPT) system for electric vehicle battery charging (EVBC) is always ever-increasing. In the WIPT inductively coupled coil structure is the heart of the system and the mutual inductance (MI) between the coupled coils is the key factor for effective power transfer. This paper presents the analysis of mutual inductance between t...
