Power transfer using non-contact- cater for future power distribution
This research work is to develop a novel transmitter architecture for a mixed-frequency wireless power transfer (WPT) system. The proposed design enables simultaneous power delivery at two distinct operating frequencies using a single inverter and a single transmitting coil. By utilizing tapped transmitter coils to form two resonant networks, the system minimizes transmission impedance and enhances power transfer efficiency at both frequencies. On the receiving side, two coils with different resonant frequencies decouple energy components, effectively suppressing frequency cross-coupling. Experimental results demonstrate the system's effectiveness, showcasing a transmission efficiency of approximately 86.2%. This innovative approach lays the groundwork for future advancements toward MHz wireless power transfer applications.
