Outline
In order to address the problems that sensitivity of traditional single-ended driven wireless power transfer (WPT) systems to positional misalignment and their reliance on detection and control mechanisms, a novel single-ended driven WPT system with misalignment tolerance is proposed. The system is based on a hybrid configuration of unipolar and bipolar coils, maintaining constant coupling magnetic flux under misalignment conditions. By utilizing orthogonal excitation from two sets of single-ended driving circuits and optimizing the parameters of the compensation circuit, the system achieves constant voltage output resistant to positional misalignment without relying on detection and control. Furthermore, the system maintains efficiency without degradation across the entire range of positional misalignment. Simulation and experimental results validate the effectiveness of the proposed anti-misalignment system, demonstrating a constant voltage output with less than 0.77% ripple under [-24.24%, 24.24%] misalignment, while achieving an efficiency of 85.14% with ripple less than 1.96%. This approach not only reduces the number of switching devices and associated driving circuits but also ensures robust offset resistance capabilities.
