Abstract: The present invention relates to a Dynamic Power Frequency Based Inductive Wireless Power Transfer (IWPT) System designed for telemetry applications and rotating machinery. The system operates at power frequency (50/60 Hz), eliminating the need for high-frequency electronics and reducing electromagnetic interference (EMI). The system consists of a static primary coil (1) connected to a power source (8) and a rotating secondary coil (2) mounted on a rotating shaft, both housed within iron cores. This configuration enhances the magnetic flux linkage, ensuring efficient power transfer with minimal energy loss. The system is capable of transferring power wirelessly to devices such as telemetry systems without complex circuitry, maintaining high efficiency even under varying rotational speeds. Experimental results and FEM simulations confirm that the system remains stable and reliable, offering a cost-effective and efficient solution for continuous power supply in dynamic environments.
