    The dynamic wireless charging system is proposed in this article to improve the performance of capacitive power transfer (CPT). The present work suggests a novel CPT-based road infrastructure for dynamic charging with vertical plate arrangements consisting of four plates. The four aluminum plates were used to formulate the coupling capacitances between the transmitter (ground side) and receiver (vehicle side) ends. To increase the mutual capacitance, a dielectric material was filled in the space between plates on the vehicle side, which also results in improved output power. Six coupling capacitances were formed between the plates, and they are calculated by ANSYS Maxwell simulation software. By the circuit simplification method, the six coupling capacitances were reduced to four. The mutual capacitance and self-capacitance values were found for positioning the plates at different distances, and then the ideal capacitance was identified. The compensation circuit parameters were designed using dynamic circuit modeling and its performance was evaluated in LTspice software. Keywords- Wireless power transfer, dynamic charging, capacitive power transfer, coupler, circuit design.
  • An Electrified Tramway Wireless Charging System for Rail Transportation Using Dynamic Capacitive Power Transfer With Four Vertical Plates

    IEEE Transactions on Transportation Electrification, 2025
    This article proposes a novel vertical dynamic capacitive power transfer (DCPT) system to enhance the power transfer of a rail transit charging system and improve the CPT performance. The present work suggests a novel CPT-based rail track infrastructure for dynamic charging with vertical plate arrangements consisting of four plates. The four aluminum plates were used to plan the coupling capacitances between the transmitter (ground side) and receiver (vehicle side) ends. To increase the mutual capacitance, a dielectric material was filled in the space between plates on the vehicle side, which also results in improved output power. Six coupling capacitances were formed between the plates, measured by ANSYS Maxwell simulation software. The circuit simplification method reduced the six coupling capacitances to four. The mutual capacitance and self-capacitance values were evaluated for positioning the plates at different distances, and then, the ideal capacitance was identified at 100 mm. The compensation circuit parameters were designed using dynamic circuit modeling, and its performance was evaluated in LTSPICE software. The hardware prototype is developed in the laboratory and operates at a 1-MHz frequency and the output power is obtained as 2.76 kW with a maximum efficiency of 92.6%.
  • Design of dual transmitter and single receiver coil to improve misalignment performance in inductive wireless power transfer system for electric vehicle charging applications
    S. Kodeeswaran, S. Julius Fusic, A. Kannabhiran, M. Nandhini Gayathri, Sanjeevikumar Padmanaban
    Results in Engineering, 2024
    • Interconnected two transmitters proposed to reduce the misalignment of the Inductive Power Transfer (IPT) system. • Double-sided LCC compensation circuit is used to improve the power transfer. • ANSYS Maxwell simulation is used to calculate self and mutual capacitance. • The circuit analysis is provided to calculate the power rating of IPT. • Simulation and experimental validation is done and output power achieves 1.95 kW with an efficiency 93.07% As electric vehicles (EVs) become more prevalent, ensuring efficient wireless charging despite vehicle misalignment is a critical challenge. This research work proposes a two-transmitter coil to reduce misalignment and improve the performance of the static inductive wireless power transfer (IWPT) system. The two transmitter coils are taken in the same dimensions, the inner terminals and outer terminals of the coils are interconnected. The current is applied to the transmitters, producing a magnetic field to transfer the power from the transmitter to the receiver. The finite element analysis carried out in the ANSYS Maxwell simulation is used to calculate the mutual and self-inductance of the proposed IWPT system. The high frequency (HF) converter produces high-frequency AC to transfer the power from the source side to the load side. The double-sided LCC compensation circuits are used on the transmitter and receiver sides to reduce the reactive power component present in the transmitted power. The rectifier on the receiver side converts AC to DC to charge the battery. To reduce misalignment and improve the efficiency of the IWPT, the proposed interconnected two transmitter terminals idea is performed well when there is a change in the position of the vehicle. The LTspice simulation and experimental result shows that the proposed system achieves 1.95 kW with an efficiency of 93.07% at an air gap of 150 mm.
  • Design of a Static Capacitive Power Transfer System with Six-Plate Coupler for Electric Vehicle Wireless Charging
    S. Kodeeswaran, M. Nandhini Gayathri, A. Kannabhiran, Sheldon S. Williamson
    IEEE Transactions on Transportation Electrification, 2024
    This article proposes a novel six-plate arrangement to improve the mutual capacitance, power transfer level, and efficiency of the static capacitive power transfer (CPT) system. The proposed vertical arrangement reduces the size and weight of the coupler compared to the conventional horizontal arrangement. The transmitter or primary side consists of four aluminum plates and the remaining two plates with mica placed in the receiver or vehicle side. The two vertical transmitter plates are placed on the outer side with a 300 mm gap, while the remaining four plates are installed between the outer plates with a 60 mm air gap. Thirteen coupling capacitances are created between these six plates to maintain strong coupling, which is reduced to four coupling capacitances after calculation. Finite element analysis (FEA) is carried out using ANSYS Maxwell simulation to determine the plate dimensions and coupling capacitances, and the simplified circuit model is simulated in LTspice. The power transfer level of the proposed system is experimentally verified at a transmitter distance of 300 mm (distance between outer plates) with an output power of 6.06 kW and an efficiency of 92.3% at a 60 mm air gap.
  • High-Power Converters and Challenges in Electric Vehicle Wireless Charging–A Review
    S. Kodeeswaran, M. Nandhini Gayathri, P. Sanjeevikumar, Rafael Peña-Alzola
    IETE Journal of Research, 2024
    This article reviews various inductive and capacitive wireless charging systems to achieve high-power infrastructures. The characteristics of SAE, ICINRP, and IEEE safety standards for wireless charging technology were highlighted. The working of compensation circuits, resonant converters, and challenges in wireless power transfer (WPT) systems was discussed. The mechanism of different compensation circuits used in the WPT was discussed in detail. In addition, the design of the converter circuit topology of inductive and capacitive power transfer systems in electric vehicle (EV) batteries was highlighted. The foreign object detection (FOD) methods that prevent output power variations due to metal/living objects in the charging environment were explored. The foreign object detection (FOD) techniques in terms of impedance variations in the primary side of the charging circuit were explained. This review on EVs would help researchers and industrialists to identify and develop novel charging infrastructure with low cost and charging time.
