感应耦合电能传输系统优化设计

Optimal Design of Inductively Coupled Power Transmission System

与传统电能传输系统相比,感应耦合电能传输(1CPT)系统具有方便、安全等优点,但因松耦合变压器初次级电能传输关系无法用匝数比简单描述,受多个变量影响,导致ICPT系统设计过程复杂,通常需根据经验和电路原理反复修改,最终得到合适参数,该方法效率很低。此处对ICPT系统进行电路建模分析,并在此基础上提出系统的优化模型,将优化设计转化成带有非线性约束条件的最优解问题,并基于1stOpt软件编程求解,实现指定目标和约束条件下的系统优化设计。该优化设计方法灵活度高,简单可行,可大大提高效率。

Compared with conventional power transmission system, inductively coupled power transmission （ICPT） system is convenient and safe.But the power relationship of loosely coupled transformer which may be influenced by many variables can not be simply described with primary and secondary turns ratio.So the design process of ICPT system is complex and cumbersome.The ICPT system is modeled and analyzed.On the base of above studies, an optimization model of the ICPT system is proposed and the design process into optimal solution is transfered with nonlinear constraints,and lstOpt is used to solve,so that the system parameters are optimal under specific objectives and constraints.The optimal design method is simple and feasible, and can greatly improve efficiency.
