论文摘要
两阶段的无线电源接收器通常包括AC-DC二极管整流器和DC-DC调节器，是低功率无线电源传输应用中的流行解决方案。但是，整流器和调节器之间的相互作用可能会在直流链接和输出电容器上引入BEAT频率振荡。在本文中，通过减轻讨论的振荡的相应设计解决方案研究了Beat频率振荡及其相关问题的原因。提供了两个阶段无线接收器系统中BEAT频率振荡的理论和实验结果。我们的研究表明，如果应用适当的设计解决方案，可以显着缓解BEAT频率振荡。
Two-stage wireless power receivers, which typically include an AC-DC diode rectifier and a DC-DC regulator, are popular solutions in low-power wireless power transfer applications. However, the interaction between the rectifier and the regulator may introduce beat frequency oscillation on both the DC-link and output capacitors. In this paper, the cause of the beat frequency oscillation and its related issues are investigated with the corresponding design solution on alleviating the oscillation discussed. Theoretical and experimental results verifying the presence of beat frequency oscillation in the two-stage wireless receiver system are provided. Our study shows that the beat frequency oscillation can be significantly alleviated if appropriate design solutions are applied.
