Abstract To combine the respective transmission efficiency advantages of the magnetically-coupled inductive wireless power transfer (MCI-WPT) in the inductive field and the magnetically-coupled resonant wireless power transfer (MCR-WPT) in the resonant field, the magnetically-coupled bi-module wireless power transfer(MCB-WPT) is presented in this paper, whose topology is changed according to the control by the state-switches.The MCB-WPT can work in the MCI-WPT mode and MCR-WPT mode with optimal transmission efficiency in the valid range.Moreover, the influence of the transmission distance on the transmission efficiency with MCI-WPT and MCR-WPT models is analyzed and the concept of MCB-WPT is proposed.Furthermore, the optimal design and control strategy is presented.The experiment shows that the high transmission efficiency can be obtained in both inductive field and resonant field with MCB-WPT.
