In this paper, a new ferrite-less wireless charging pad, called circular nonferrite pad, for roadway applications is introduced. The pad is characterized by having the ability to control leakage flux to reduce the electromagnetic fields outside the charging region. In addition, the pad shows low sensitivity to changes in the self-inductance due to secondary pad misalignment. A comparison of this new...
Shaping of the magnetic field between the primary and secondary coils of Inductive Power Transfer Systems is crucial for system performance and to keep leakage within emissions guidelines. This paper gives an overview of different methods used to shape the magnetic field, followed by work done by the authors looking into one of these methods for use in an electric vehicle charging application using...
Inductive Power Transfer (IPT) systems have been proposed for various applications and have been increasingly gaining interest for electric vehicle (EV) charging. Numerous magnetic structures have been proposed for IPT systems for EV charging including structures involving mutually decoupled coils. This paper presents an analytical model of an IPT system composed of a two coil primary pad and a single...
This paper introduces a new ferrite-less magnetic structure for roadway charging of Electric Vehicles (EVs). Most of the existing magnetic pads for roadside EV charging rely on ferrimagnetic materials to produce single-sided flux and boost power levels while minimizing undesired field emissions and losses. But the properties that roadway pads must have are mechanical robustness coupled with the ability...
This paper presents a method and circuit for correcting faults in logic systems. The method, called "restorative feedback" (RFB), is similar in some respects to triple modular redundancy (TMR), but has an improved error probability with respect to transient errors. Simulation results indicate an improvement by about two orders of magnitude compared to traditional TMR. CMOS circuits are presented...
