Summary:Magnetically-coupled resonant wireless power transfer (MCR-WPT) offers a novel technique to transfer power over a long distance with high efficiency. A half bridge inverter with series-resonant structure is designed as driver source for WPT system in this paper. The frequency is up to 0.9MHz, which is very higher than traditional power electronic converter. The relationship between output power, transmission efficiency and load resistance, transmission distance is analyzed by mutual inductance theory and verified by experiments, respectively. Then the critical values of load and distance are obtained. Parameters and experimental results of the system are also presented in this paper. Experiment proved that the series-resonant half bridge inverter can be easily designed to achieve wireless power transfer with good performance.
