There is a big error in the classic DV-Hop localization algorithm in average hop distance and unknown point coordinates. We propose an improved DV-Hop location algorithm, by improving the average hop distance and introducing a checkout algorithm in the second and third stages of the classic DV-Hop localization algorithm, to improve the position accuracy. The MATLAB simulation shows that in the same...
In order to optimize the power transfer capability of a contactless power transfer (CPT) system with multi-load, this paper has analyzed the existence condition of the maximum power transfer capability of a CPT system with a certain topology and parameters based on impedance analysis. In addition, a procedure of optimized design is given according to the need of the power and efficiency requirement...
This paper presents a power control strategy based on multi-resonant operating points, which is realized by multilayer feedforward neural network applying back-propagation algorithm. The full-bridge contactless power transfer system and magnetizing current of the transmitter on primary side are respectively used as research object and control variable. After batch-learning and training, the converged...
In Inductively Coupled Power Transfer (ICPT) system, attribute to unidirectional energy transfer, there are many problems such as energy feedback difficultly and low efficiency brought by system open-loop running. This paper put forwards a novel contactless energy bi-directional transfer mode to realize energy exchange between transmitter and receiver. The paper presents a bi-directional energy conversion...
The paper present comparison analysis of current soft-switched methods. Series resonant full bridge topology and parallel resonant full bridge topology were choose for their sine wave current in inductor, which meet requirement of Contactless Power Transfer (CPT) system. The paper also presents a detailed simulation and analysis between series resonant and parallel resonant full bridge topologies...
