旋转式松耦合变压器的绕组优化设计
|
摘要
旋转式无线励磁系统的核心部件松耦合变压器因存在大气隙,导致其漏感较大,无法有效地提高耦合系数,从而限制了系统效率的提升。为解决该问题,首先对旋转式松耦合变压器进行等效建模与漏感分析,针对常见绕组存在的缺陷进行了改进设计,提出PCB绕组结构。利用Ansys/Maxwell仿真分析软件确定该优化结构的可行性。设计S-S谐振补偿方案,运用Simplorer与Maxwell进行联合仿真,进一步验证该方案的优化程度。最后搭建实验平台,对改进前后松耦合变压器在较大气隙条件下的耦合系数与传输效率进行对比,验证了所提方案的合理性。
The loosely coupled transformer,which is the core mechanism of the rotary wireless excitation system,has a large air gap.As a result,the leakage inductance is large,which makes the coupling coefficient cannot be validly improved,and also the improvement of the system efficiency is limited.In order to solve this problem,the equivalent model is established and leakage inductance is analyzed for the rotary loosely coupled transformer firstly.Aiming at the defects existing in the common winding and the PCB winding is proposed.The feasibility of the optimized structure is determined by using Ansys/Maxwell simulation analysis software.The S-S resonance compensation scheme is designed,then the Simplorer and Maxwell are used for co-simulation to further verify the optimization of the scheme.An experimental platform is set up to compare the coupling coefficient and transmission efficiency of the improved loosely coupled transformer under a large air gap condition,which verified the rationality of the proposed scheme.
