摘要
在无线电力传输领域,必须考虑发射和接收线圈之间的不对准问题。当耦合系数发生波动时,传统的无线电力传输系统的输出功率会显著下降。本文提出了一种可重新配置的双频串联(SS)拓扑结构,其一次侧为电感失谐,二次侧为全谐振。所提出的拓扑结构可在两个频率下工作,并可在每个频率下转换成两种不同的 SS 拓扑结构。这样,当出现较大偏差时,系统就能在两种 SS 拓扑之间切换,从而获得更稳定的输出功率水平。此外,还介绍了拟议拓扑结构的综合参数设计流程图,并设计和实现了 400 W 原型的参数。对原型进行了测试,以评估拓扑结构的性能。原型的频率响应分析验证了参数设计方法的有效性。测试结果表明,该拓扑结构能在 k = 0.13 到 k = 0.46 的偏差范围内将输出功率波动保持在最大功率的 23% 以内。此外,该系统在整个输出功率平坦范围内的效率至少为 80%,最高效率可达 91%。
Reconfigurable detuned dual-frequency series–series compensated WPT system for high anti-misalignment tolerance
In the realm of wireless power transfer, considering misalignment between transmitting and receiving coils is imperative. Traditional wireless power transfer systems experience a significant decrease in output power when the coupling coefficient fluctuates. This paper proposes a reconfigurable dual-frequency series–series (SS) topology with primary side inductive detuned and secondary side with full resonance. The proposed topology operates at two frequencies and can be transformed into two different SS topologies at each frequency. This allows the system to switch between the two SS topologies when a large misalignment occurs, thereby achieving a more stable output power level. Furthermore, a comprehensive parameter design flowchart for the proposed topology is presented, and the parameters for a 400 W prototype are designed and implemented. The prototype is tested to evaluate the performance of the topology. The frequency response analysis of the prototype validates the effectiveness of the parameter design method. The test results show that the topology can maintain output power fluctuations within 23% of the maximum power for misalignment ranging from k = 0.13 to k = 0.46. Additionally, the system maintains an efficiency of at least 80% across the entire output power flat range, peaking at a maximum efficiency of 91%.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
