Abstract:To solve the issue of energy feedback difficultly and low efficiency brought by system open-loop running caused by unidirectional energy transfer in traditional inductive coupled power transfer (ICPT) system, a novel multi-load inductive coupled power bi-directional transfer mode was proposed to realize direct conversion between energy transmitter and receiver. The general principle about multi-load inductive coupled power bi-directional transfer based on energy injection mode and autonomous running mode was discussed, and at the same time, the topology of multi-load high frequency energy bi-directional transfer with resonant soft-switched technology was put forward to fulfill the energy bi-directional transfer requirement. Furthermore, the corresponding state-space model with energy injection mode and autonomous running mode and the topology parameters design method of resonant part for the maximum power transfer capability were analyzed. Finally, the simulation results validate the validity of multi-load inductive coupled power bi-directional transfer mode.
