Abstract
This paper presents an innovative adaptive strategy implemented in wireless power transmission (WPT) systems to overcome efficiency challenges due to coupling structure misalignment and load variability. A novel versatile transmitter, capable of alternating between single and dual voltage source states via two MOSFETs has been designed. Initially, the system operates in a single voltage source mode, mutual inductance and load characteristics are pinpointed using a particle swarm optimization algorithm. Subsequently, the system transitions to dual voltage source mode, where it fine-tunes the auxiliary voltage source's amplitude and phase based on the determined mutual inductance and load values to realize zero phase angle for optimal impedance matching. The experimental results show that this method can obviously improve the output power of WPT system. This method stands out for its simplicity, adaptability and rapid response, suggesting its potential for practical use in dynamic charging applications.
