20.500.12556/DKUM-92307 Control of an inductive power transfer system using a double coil structure This paper presents the design of the control of the system using a double DD coil structure. The double DD coil is a layered coil structure that consists of two single DD coils, rotated to each other by 90◦. A large-signal and small-signal model of the proposed IPT system are designed for control synthesis. The small-signal model is derived from the large-signal using harmonic approximation and the extended describing functions (EDF). For the small-signal model, voltage and current control schemes were proposed for the purpose of wireless battery charging. The robustness of the control is tested on a small-scale IPT system using double DD coils and resistive load. The results are evaluated at different reference voltages, currents, loads and coupling coefficients. wireless power transfer double DD coil structure voltage control IPT with multiple coils brezžični prenos energije dvojna struktura tuljave kontrola napetosti true false true MDPI AG Angleški jezik Slovenski jezik https://www.mdpi.com/journal/electronics © 2022 by the authors Članek v reviji 2025-03-28 08:45:20 2025-03-28 08:45:20 2025-03-29 03:12:47 0000-00-00 00:00:00 2022 0 0 25 str. iss. 14 Vol. 11 8 July 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2022-05-05 2022-07-06 2022-07-08 621.314.572 118034435 10.3390/electronics11142148 2079-9292 electronics-11-02148-v2.pdf electronics-11-02148-v2.pdf 1 1D881F2AD57C7914697A241CE83E1B52 f640270755a47441112ad422c9e39d4fbbd72191aba564b07884cdeda5106f19 d6309b61-0ba8-11f0-af5a-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=189765 https://www.mdpi.com/2079-9292/11/14/2148 0 dadd841c-0ba8-11f0-af5a-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=189766 Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
