摘要: 针对传统感应耦合电能传输(ICPT)系统的工作状态随负载变化而偏离最佳工作点的问题，在ICPT系统中引入H桥变流器取代传统补偿电容，通过改变其触发角实现补偿容量动态调节和最佳工作点跟踪。根据电路互感理论建立ICPT系统最佳工作点下的补偿容量-负载匹配数学模型，并以最大功率点为优化目标，给出了基于H桥变流器动态补偿的ICPT拓扑及阻抗匹配控制方法。Matlab仿真结果表明，H桥变流器触发角α的取值范围为α＜40°。实验结果表明，基于H桥变流器动态补偿的ICPT拓扑具有良好的动态补偿特性，能够在负载变化时自动跟踪系统最佳工作点。Abstract: In view of problem that working state of traditional inductive coupled power transmission (ICPT) system deviates from optimal operating point as the load changes, H-bridge converter is introduced to replace traditional compensation capacitor in ICPT system, and dynamic adjustment of compensation capacity and tracking of optimal operating points are achieved by changing its trigger angle. Compensation capacity-load matching mathematical model under optimal operating point of ICPT system is established according to circuit mutual inductance theory. The maximum power point is used as the optimization target, and ICPT topology and impedance matching control method based on dynamic compensation of H-bridge converter are given. Matlab simulation results show that the range of trigger angle α of H-bridge converter is α<40°; experimental results show that the ICPT topology based on dynamic compensation of H-bridge converter has good dynamic compensation characteristics, which can automatically track the optimal operating point of ICPT system as the load changes.
