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...

Optimum Structures of a Cascaded Multilevel Inverter for Minimum Number of Power Electronic Devices

In this paper, several optimum structures of a cascaded multilevel inverter is proposed. This optimization is based on generation a constant number of output voltage levels by using minimum number of power switches or dc voltage sources or minimum amount of blocked voltage by power switches. In addition, the optimum structure for a constant number of dc voltage sources by using minimum number o...

Compensation topology for flat spiral coil inductive power transfer systems

Inductive power transfer technology is now widely used to provide power into various devices, such as battery based vehicles, implant devices, portable equipment etc. Despite the rapid development of power electronics components, inductive power transfer technology still has some drawbacks. The output power is vulnerable to the magnetic coupling efficiency of two coils. If misalignment and disp...

Complex Coil Assisted Single Coil Embolization for Small Intracranial Aneurysm

The purpose of the technical note is to introduce the complex coil assisted coil embolization method in the treatment of intracranial small aneurysm, in order to enhance the safety of the procedure. The first microcatheter was navigated into the aneurysm sac and the ultrasoft coil was used as the embolization coil. If the embolizations coil could not stay within the aneurysm sac smoothly, such ...
