    Robust Wireless Power Transfer for EVs by Self-Oscillating Controlled Inverters and Identical Single-Coil Transmitting and Receiving Pads by Alireza Eikani, Mohammad Amirkhani, Ehsan Farmahini Farahani, Volker Pickert, Mojtaba Mirsalim, Sadegh Vaez-Zadeh

    Published 2025-01-01
    “…This paper, for the first time, develops a robust IWPT system using a circular pad (CP) and double-D pad (DDP) with a self-oscillating controlled inverter (SOCI), which offers high steady output power and transfer efficiency under magnetic coupling variations simply with feedback from the transmitter-side current. The compact 2CP and 2DDP magnetic couplers with single identical coils are robust to self- and mutual-inductance variations, so the IWPT system exhibits greater robustness at increased transfer distances (air gaps), as well as in the presence of lateral and rotational misalignments between the two magnetic pads, compared to couplers using nonidentical transmitting primary (TP) and receiving secondary (RS) pads and numerous decoupled coils on the RS pad. …”
