摘　　要：针对信号与电能同步传输的感应耦合电能传输(ICPT)系统中信号耦合线圈对电能传输效率影响的问题,基于LCLP型ICPT系统谐振拓扑结构,利用在原、副边增设耦合线圈对信号进行加载和拾取,实现了信号与电能的同步传输;通过分析原、副边电流的关系,利用耦合变压器、信号发射耦合线圈和信号接收耦合线圈的互感反射阻抗,建立了信号耦合线圈与电能传输效率之间相关联的非线性规划模型,分析了信号耦合线圈对传输效率的影响,给出了相对应的电能传输效率目标函数和约束条件,在此基础上利用自适应粒子群优化算法对谐振补偿参数进行优化,并进行了仿真验证。仿真结果表明相较于同类型信号传输方法,优化后的系统信号传输误码率有所降低,电能传输效率有所提高;波特图表明优化后的信号传输电路并未对电能传输造成较大影响,负载处谐波畸变率有所降低。Aiming at the problem of the effect of the signal coupling coil on the power transmission efficiency in the ICPT(Inductively Coupled Power Transfer)system considering the influence on synchronous transmission of signal and power energy.Based on the LCLP-type resonance topology structure of ICPT system,additional coupling coils are added on the primary and secondary sides to load and pick up the signal,and the synchronous transmission of signal and power energy is realized.By analyzing the current relationship between the primary and secon-dary sides,the nonlinear programming model that correlates the signal coupling coil with the power transmission efficiency is established by using the mutual inductance reflection impedance of coupled transformer,signal transmitting coupling coil and signal receiving coupling coil.Then,the influence of the signal coupling coil on the transmission efficiency is analyzed,and the corresponding objective function and constraints of the power transmission efficiency are given.On this basis,adaptive particle swarm optimization is used to optimize the resonance compensation parameters,and simulation verification is performed.Simulative results show that compared with the same type of signal transmission method,the optimized system signal trans-mission error rate has been reduced and the power transmission efficiency has been improved.The Bode diagram shows that the optimized signal transmission circuit does not have a large impact on the power transmission,and the harmonic distortion rate at the load is reduced.
