A Dynamic Reconstruction Strategy for Adaptive Power Receiving of Moving Targets in MPT System

The fixed connection receiver has great limitations for moving targets with variable power transmission distance or position offset in MPT system. To solve the problem, a dynamic reconfiguration strategy of DC side switch is proposed to improve the efficiency of rectification system at spatial scale. Firstly, a connection mode of rectenna array with voltage equalization is presented according to the power distribution law of receiver end. Secondly, based on the variable DC switch topology of the distributed receiver, an evaluation model of the dynamic reconstruction considering the power violation is established, and then combining with the control strategy can get the optimum reconfiguration mode under different conditions. Finally, the effectiveness of the proposed model and method is proved by simulation and experiment.
