PT对称多线圈并联无线电能传输系统参数优化
Parameter optimization of PT symmetry multi-coil parallel wireless power transfer system
摘要
Abstract
The parameters of Parity-Time (PT) symmetry multi-coil parallel wireless power transfer (WPT) system are interrelated and to configure them is difficult.This paper proposes a PT symmetry-based multi-coil parallel wireless power transfer system parameter optimization design method.First, a mathematical model of PT-symmetric multi-coil parallel WPT system is built, and the general influence law expressions of system output power, transmission efficiency and effective transmission distance are given.Second, an optimization method combining nonlinear programming and genetic algorithm is adopted to optimize the number of transmitter-receiver coils and resonance parameters of the system with the output power as the objective function and the transmission efficiency and effective transmission distance as the constraints.Finally, an experimental prototype is built according to the optimization results.Our experimental results show the system power output meets the design requirements under the required transmission efficiency and effective transmission distance, demonstrating the effectiveness of the theoretical analysis and optimization method.关键词
