| ABSTRACT |
|
For wireless power transfer system (WPT), the delay of communication between primary side and secondary
side influences the robustness of system. This paper proposes a bilateral control strategy based on the LCL-S compensation
network wireless charging system without communication. The proposed bilateral control strategy adopts disturbance control
to optimize efficiency on primary side, and proportional-integral (PI) control to adjust the charging current/voltage on
secondary side, which realizes the separation of control between the primary and secondary side. The feasibility of proposed
bilateral control strategy is verified through simulation and experiment. Based on the realization of CC mode and CV mode,
the efficiency of the system is improved remarkably. |
