As a new power transmission technology, magnetically coupled resonant wireless power transmission technology can achieve mid-range wireless power transmission with the advantage of high transmission efficiency. As known, the driving source has a significant impact on the overall performance of wireless power transmission system. With this consideration, a pulse-driven magnetically coupled resonant wireless power transmission system is proposed herein. The circuit model of the system is established on mutual inductance coupling theory. Through the analysis of its working mode the mathematical models of load power and transmission efficiency are established and the relationships among load power, transmission efficiency and driving signal frequency, duty cycle and transmission distance are revealed. Subsequently, a pulse-driven magnetically coupled resonant wireless power transmission prototype is designed and the experiment is conducted by using control variables method. The authenticity of the theory is verified as well by experiments. In the experiment, the system realizes wireless power transmission of load power 1.17W and transmission efficiency 76.13% under the condition of DC voltage 12V, driving signal frequency 94 KHz and duty cycle 15%.
