This paper presents a fuzzy based synchronization scheme for grid connected three phase Bidirectional Contactless Power Transfer (BCPT) system suitable for Electric Vehicle and Plug-in-Hybrid Electric Vehicle. The proposed synchronization scheme estimates the phase angle directly by tracking the grid voltage and frequency variations and facilitates synchronization of BCPT system with grid for c...

-In this paper, we designed and implemented an integrated circuit for contactless interface transmission system to conform the transfer protocol of ISO/IEC 144432 Type B. The system consists of two major parts, interrogator and transponder, for magnetic power and data transmission. The power and data can be transferred to the transponder synchronously from the interrogator by the 10% ASK modula...

This paper deals with a generic methodology to evaluate the magnetic parameters of contactless power transfer systems. Neumann’s integral has been used to create a matrix method that can model the magnetics of single coils (circle, square, rectangle). The principle of superposition has been utilized to extend the theory to multi-coil geometries, such as double circular, double rectangle and dou...

We have designed an asynchronous chip for contactless smart cards. Asynchronous circuits have two power properties that make them very suitable for contactless devices: low average power and small current peaks. The fact that asynchronous circuits operate over a wide range of the supply voltage, while automatically adapting their speed, has been used to obtain a circuit that is very resilient t...

Abstract At present, contact watertight connectors are commonly utilized for the connection between underwater electromechanical equipment and seabed observation network. Such conventional inevitably likely to be irreversibly worn when plugging unplugging, besides complicated sealing structures limited service life. This paper designs a Wet-Mateable connector aiming Contactless Power Transfer O...

Abstract—Transferring electrical power without any wiring has been a dream since late 19th century. There were some advances in this area as to know more about microwave systems. However, this subject has recently become very attractive due to their practiScal systems. There are low power applications such as charging the batteries of contactless tooth brushes or implanted devices, and higher p...

The concept of modern decentralized transport system consists not only of the drive and control technology, but also the transmission of data and energy. The latter tends to play a more important role in the future. In this paper we focus on the contactless data transmission system over the power-line cable, which is used for a contactless current supply. An implementation of the FPGA based OFD...
