Design of loosely coupled inductive power transfer systems

Abstract: A design methodology for loosely coupled inductive power transfer systems is proposed. Such systems are used for noncontact power transfer, often over large airgaps to moving loads. Due to the large leakage inductances that result, compensation is usually necessary to achieve the required power transfer capability. The level of compensation, as well as possible compensation topologies, are discussed in the paper. Special attention is paid to the tradeoffs involved during the design process.

A transmission line model for high-frequency power line communication channel

Abstract: This paper presents a novel approach to modelling the transfer function of the broadband power line communication channel. In the approach, the power line is firstly approximated as a two-wire transmission line. The two intrinsic line parameters, the characteristic impedance and the propagation constant, are derived based on the transmission line theory. Then from the derived line parameters, an echo-based model is used to determine the transfer function for communication signals in the frequency range of 1 MHz-30 MHz. This approach reaps the advantages of accuracy and simplicity of the conventional modeling approaches.

Parameter design principle of the arm inductor in modular multilevel converter based HVDC

Abstract: This paper describes two distinctive functions of the arm inductor in the modular multilevel converters (MMC): suppressing the circulating current and limiting the fault current rise rate. Based on the equality of the instantaneous power, the characteristics of the circulating current are analyzed and demonstrated that it flows through the three phase of the converter in negative sequence at double-fundamental frequency. The relationship between the amplitude of the circulating current and the value of the arm inductor is discussed, and the first principle to design the parameters is proposed. The second principle to design the parameters is based on the calculation of the fault current rise rates, with different values of the arm inductors. A detailed PSCAD/EMTDC model of MMC is developed. Steady state simulation proves the existence of the circulating current at double fundamental frequency. Simulation results show a close agreement with the calculation of the circulating current, with different arm inductor parameters. The fault between the DC terminals of the converter is investigated; the results verify the above parameter design principles of the arm inductor.

The design of a contact-less energy transfer system for a people mover system

Abstract: This paper describes a contactless power transfer system to provide intervention free battery charging to a specially designed low weight electric vehicle for use in an historic New Zealand national park. The noncontact feature of the ICPT (inductively coupled power transfer) system is significant in that the charging is transparent to the driver. When the driver stops at the loading platform, the charging unit automatically senses the vehicle and begins charging if required. Four charging bays (buried under the ground) are provided allowing opportunity charging throughout the day. This minimises the necessary on-board batteries, and therefore the vehicle weight, while still allowing the vehicles to be operated continuously.
