感应耦合传输系统的建模分析

Modeling analysis of inductive coupling power transmission system

针对非接触电能传输(ICPT)系统负载变换时造成原边回路电流不能保持恒定的问题,介绍了一种新型的基于LCL谐振补偿网络的ICPT系统拓扑结构。建模分析了基于LCL补偿的ICPT系统的等效电路模型,并对LCL型ICPT系统所表现出的恒流、恒压特性进行仿真分析和验证,为ICPT系统的设计和分析提供了良好思路。

As regard to the problem of the current of the primary loop cannot be constantly maintained due to the ICPT load changes, a new type of ICPT topology based on LCL resonant compensating network is proposed. The equivalent circuit model of the ICPT system based on LCL compensation is established and analyzed. The constant current and constant voltage properties showed by the ICPT system are analyzed and verified by Matlab simulation, and which provide a good thinking for design and analysis of the ICVI＂ system.
