Abstract
A driving device for magnetic coupled resonant wireless energy transfer system is explored, and its equivalent circuit model is established. By analyzing driving device's operation mode and time-domain waveform, mathematical expressions of loss and efficiency are obtained. Conditions for power transistors working at soft switching mode are analyzed along with the relationship between fundamental component under different duty cycles and voltage stress of power transistors. Simulation and experimental results show that the device can be used for wireless power transfer technology, and it is of certain practical value.
