    Analysis of Mutual Inductance between Asymmetrical Spiral Circular Coils of WIPTS for EV Battery Charging
    (Institute of Electrical and Electronics Engineers Inc., 2020) Kishan, D.; Vinod, M.
    Wireless Inductive Power Transfer System (WIPTS) for electric vehicle battery charging is an emerging technology. It enables electric power transmission without any physical connection between the transmitter coil (Tx) and receiver coil (Rx) over a certain distance. However, the power transfer capability between the wirelessly coupled inductive coils is greatly affected by mutual inductance (MI) between them. This paper presents a new analytical method based on Neumann's equation for computation of MI between the asymmetrical spiral circular coupled coils. The computed mutual inductances are validated with Finite Element Modeling (ANSYS MAXWELL) simulation results. The relative error between the analytical and FEM simulated results is negligible. © 2020 IEEE.

    Magnetic Coupling Characteristics of Spiral Square - Circular Coupled Coils for Wireless EV Battery Charging System
    (Institute of Electrical and Electronics Engineers Inc., 2020) Kishan, D.; Vinod, M.; Nagendrappa, N.
    Electric Vehicles (EVs) are gaining continuous interest due to higher efficiency than internal combustion engine vehicles, and environmentally friendly nature. Nowadays, most of the EV uses the conductive charging method to charge the battery. Besides that, wireless inductive charging technology for EV has recently received a great attention because of the advantages such as increased user convenience and safety. In this method of charging mutual inductance between the wireless inductive coils is the crucial factor. Hence, this paper describes the mutual inductance characteristics of the transmitter with spiral square - receiver with circular (i.e., interoperability spiral square and spiral circular of coils) at various vertical distances using FEM simulations. © 2020 IEEE.

    Design of Spiral Square Inductive Power Pads with Misalignment for Wireless Power Transfer System
    (Institute of Electrical and Electronics Engineers Inc., 2021) Vinod, M.; Kishan, D.; Nagendrappa, H.; Kannan, R.
    Wireless power transfer (WPT) can find the potential applications reaching from power transfer to low power appliances to high power electric vehicle battery charging and industrial systems applications. Inductive power pads are the key components for magnetic induction based WPT systems. Hence, this paper labels the analysis of magnetic coupling characteristics of spiral square inductive pads with various misalignments. In this process the inductive power pads are designed in FEM simulation. The modelling approach is presented to calculate the coupling coefficient, self and mutual inductance of spiral square inductive pads of WPT system and also presented the power and efficiency analysis of the system. © 2021 IEEE.
