“…This is with reference to Fig. 5 depicting the cross couplings, where it shows that further the coil away from the excited coil, lower the effect of the cross couplings as 12 and 23 are significantly higher than 13 , and cross couplings would be negligible for more than two coils away from the excited coil. The simulation and theoretical waveforms of the transmitter current, , and LCC primary loop current, , , are shown in Fig.…”

“…This leads to high electromagnetic interferences and a high level of electromagnetic exposure from the non-interactive parts of the transmitter. In terms of electric concerns, power losses in the non-interactive part of the transmitter and the size of compensators and power supplies to drive the transmitter are the main drawbacks of the elongated transmitter [4,[10][11][12][13][14][15]. Moreover, the reliability of the system is dependent on the length of the transmitter, and in case of any failure, all the length of coverage would malfunction.…”

Expandable and flexible wireless power transfer (WPT) systems have been in demand in numerous industry applications, especially for dynamic chargers in electric vehicles. Those systems, however, brings about certain technical issues such as modulation technique and topology of the transmitter-side, and transferred power profile of the transmitters. In this paper, a new converter topology to drive closely spaced segmented Dynamic Wireless Power Transfer (DWPT) systems is proposed. The proposed converter can be expanded to cater for different number of transmitters, and it can provide a uniform transferred power profile throughout the path of transmitter coils, known as track. Furthermore, this study focuses on analyzing the operation of the converter and the effect of closely spaced transmitters over its operation. To show the effectiveness of the proposed topology and its modulation technique, the converter is simulated and experimentally tested using a laboratory prototype. The results are compared and analyzed, and their close agreement shows the validity of the proposed technique.

 Abstract-This paper discusses the transient control of a system for dynamic inductive power transfer to an electric vehicle when passing a road-side coil section. A series-seriescompensated topology with minimum number of passive components is assumed and a slight detuning of the resonance frequencies is introduced to limit the maximum induced current on the vehicle-side. A simple strategy for independent control of the road-side and vehicle-side coils is presented for ensuring strictly controlled charging power. The dynamic response of the resonant currents and of the power transfer is assessed by a small-scale experimental setup designed to represent a freight truck in scale 1:14. Experimental evaluation of the energy transfer efficiency is performed for high and low vehicle speeds and with different strategies for activating the control loops. The results demonstrate that the proposed strategy can ensure very short initialization transients and close-to-optimal operation at rated power when the vehicle-side coil is passing above the roadside coil, even at relatively high traveling speed. The concept of road utilization ratio is introduced to quantify the effect of length and layout of the road coil sections, as well as the dynamic transients, on the energy transfer capability of the system.

“…In future is predicted that energy storage systems and HEVs or EVs in-vehicle batteries will share power as a requirement or contribute interconnected with grid power to peak cuts or peak shifts of power consumption in the coming years of smart grids. In such a part, the important role will play a series bidirectional DC-DC converters [1][2][3][4][5][6]. Additionally, DC-DC converters can be used for charge/discharge management of rechargeable batteries but for various types like including automated guided vehicles (AGVs) of industrial equipment elevators, cranes.…”

To Analyze wireless charging system of solar PV, panel concept with electric vehicle (EV). In this developed type is a combination of solar photovoltaic (PV) and Micro grid. In this type, designed two type of operation initially the EV Charging with micro grid input supply and PV Panel. If any fault occur or grid power failure the EV battery system charge through PV panel ultimately the battery sys-tem always on line charging either grid source or PV arrays panel. The proposed methods are integrated with bidirectional converter back-to-back converter with grid source. This paper focus into the power enhancement depends upon the irradiation of solar panels, so that the conversion of electrical energy is in accordance with the needs of electric vehicle attain maximum as possible. The design type of EV wireless charging methodology analyzed using MATLAB/Simulink is to get the effective power enhancement and charging to the electric vehicle continuous on line charging system.
