| Summary: | AbstractIn this article, a wireless power transfer (WPT) system with a single transmitter to power multiple electronic loads simultaneously using multiple receivers is proposed. We analyzed various types of coil geometries on the receiver side, including circular, square, hexagonal and octagonal shapes. Then, employing the finite element analysis (FEA) method with the ANSYS MAXWELL simulation tool, we identified the most efficient coil design system based on parameters, such as self-inductance, mutual inductance and coefficient of coupling factor. Subsequently, the electrical parameters necessary for the proposed concept were calculated from the equivalent circuit model and simulation of the proposed model was performed using the LT-Spice simulation tool. An 85 kHz resonant frequency was achieved using a high-frequency inverter (HFI), and inductor-capacitor-capacitor (LCC) compensation topologies were employed to provide different power capabilities to the loads.
