“…IPT is a well proven wireless power transfer technique which is intended here to power to the modules [4][5][6][7][8]. IPT is based on Ampere's and Faraday's laws which state that an electric current flowing in a an extended loop of wire (track) will produce a magnetic field and that this magnetic field will induce a voltage in a coil of wire (pick-up) when it is placed in proximity with the track.…”

Abstract-Flexible manufacturing systems (FMS) and reconfigurable manufacturing systems (RMS) have both recently evolved to meet increasing demands for flexible manufacturing. This paper investigates the possibility of contact-less power and wireless data transfer to increase the flexibility and safety of various FMS modules by eliminating the need for power or data connections. The paper discusses advantages and implementation aspects of the proposed inductive power transfer (IPT) system and feasibility tests are undertaken to ensure the compatibility of IPT and the FMS modules, which form part of a lab-size modular test bed. In order to increase the cost effectiveness of the design, each module will run for an eight hour shift using a battery which is then automatically recharged via IPT. An energy aware custom switch mode charger has been designed and tested.A greedy heuristic (IEC 61499 compliant) scheduler is implemented to optimize the production schedule based on the level of charge. Design requirements for the charger, energy monitor and scheduler are discussed followed by performance results. The IPT system has been specified however it is still to be incorporated in to the final system.

“…The rural environment is challenging due to problems involving pick-up misalignment, high speeds, and excessive reactive power consumption. However, recent advancements in WPT technology have alleviated some of these problems [4][5][6][7][8][9]. In [10] a practical implementation of a highway WPT system is designed, and a prototype is tested.…”

This paper analyzes two different transportation electrification charging schemes, i.e., an embedded wireless power transfer system and an overhead catenary wire system, for use in range extension of electric vehicles on rural highways. The efficiency, feasibility, and benefits of the two schemes are examined. Electric vehicles currently lack widespread popularity mainly due to battery limitations, especially for long distance travel. The rural highway charging methods presented here can greatly increase the range of electric vehicles while decreasing battery sizes. Average modeling approaches for power electronics and vehicle usage were developed in MATLAB/Simulink to compare the two systems, each at two power levels. 30 kW and 48 kW were chosen to demonstrate the differences between power levels, both capable of maintaining a positive net charge on a dynamic electric vehicle.Component efficiencies, energy transfer levels, and installation percentages for the various models were determined. The models were applied to California highway I-5 to show immense potential savings over gasoline vehicles. It was shown that catenary charging is cheaper and has higher energy transfer than wireless; however, it has difficulty servicing all vehicle types, has visible wires, and requires more maintenance. A small scale hardware prototype of the WPT system was created in order to demonstrate the feasibility of power transfer at the proposed relative distances and speeds.

“…A DC inductor L DC is normally added after the rectifier to maintain a continuous current flow, so that the available power of the secondary pickup can be fully delivered to the load. The output voltage regulation is normally achieved by using a well-known control technique called "Shorting-Control" (Boys et al, 2000;Elliot et al, 1995;Raabe et al, 2007). Its working principle is similar to a boost converter.…”
