Misalignment tolerable coil structure for biomedical applications with wireless power transfer

2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013
Coil-misalignment is one of the major hurdles for inductively coupled wireless power transfer in applications like retinal prosthesis. Weak magnetic flux linkage due to coil misalignments would significantly impair the power efficiency. A novel receiver configuration with high misalignment tolerance is presented in this paper.

Misalignment Tolerance of Electric Vehicle Wireless Charging System Based on Reconfigurable Adaptive Topology and Centrosymmetric Coils

IEEE transactions on power electronics
In wireless power transfer systems for electric vehicles, coil misalignment is inevitable in most charging situations. Most present studies concentrate on the misalignment tolerance in one direction, either in the X, Y, Z, or diagonal directions, but ...

Misalignment tolerance analysis of free-space optical interconnects via statistical methods

Applied Optics, 2002
System-level packaging is one of the critical issues that need to be addressed for free space optical interconnections (FSOI) to become useful in desktop systems. The performance of FSOI, e.g., in terms of system bit-error rate, is greatly affected by misalignments in the optical system.

Enhancing Misalignment Tolerance in Inductive Power Transfer Systems

Inductive Power Transfer (IPT) systems have been increasingly recognized for their potential in electric mobility applications, primarily for their capability to transmit power wirelessly. However, the efficiency and robustness of these systems are often compromised due to misalignments between the transmitter and receiver coils.

Hybrid Bidirectional Wireless EV Charging System Tolerant to Pad Misalignment

IEEE Transactions on Industrial Electronics, 2017
Electric vehicles (EVs) are becoming increasingly popular as a means of future transport for sustainable living. However, wireless charging of EVs poses a number of challenges related to interoperability, safety, pad misalignment, etc. In particular, pad misalignments invariably cause changes in system parameters which in turn lead to increase in ...

Design of Misalignment Tolerant WPT System for Deep Brain Stimulator

2019 IEEE 5th International Conference for Convergence in Technology (I2CT), 2019
The paper presents the wireless power transfer (WPT) system for Deep Brain Stimulator. In WPT system, low coupling factor (k) and misalignment are the two challenges due to size limitation of implanted coils. In this paper, the design details of two and four coil systems are discussed.
