Abstract:
Research on wireless power transfer (WPT) systems, especially single-input multiple-output (SIMO) designs, has attracted significant interest due to their practicality. Nevertheless, existing multiple-output WPT systems face various challenges, including the inability to independently control the output levels at each port, reliance on specific decoupling coil structures, and poor space utilization. To address these issues, this paper introduces a novel compensation topology capable of achieving independently adjustable dual constant voltage (CV) outputs exploiting its inherent structural attributes. The proposed system employs fewer passive compensation components, thereby reducing its volume and cost. Furthermore, this design does not require complex closed-loop control strategies, simplifying the difficulty of controller design. Instead, it simply requires adjustments to the compensation component parameters to achieve the desired dual CV output levels, thereby ensuring system flexibility. Initially, a theoretical analysis is conducted, followed by simulation verification, and finally, an experimental prototype is constructed to validate the feasibility of the proposed system. © 1986-2012 IEEE.
