This paper presents a compensation network with multiple resonating frequencies for multiple-pickup wireless power transfer (WPT) systems, which aims to establish multiple channels to deliver the power to multiple loads simultaneously. In previous studies, a number of efforts have been made to realize the multichannel transmission by utilizing multiple transmitting coils or transformer to deliver power at different frequencies, which inevitably results in the extra power loss. Although loads can be energized simultaneously, the transmission performance and the maintainability of WPT systems are both deteriorated significantly. In order to address the issue, this paper proposes and implements the multiple-frequency resonating compensation (MFRC) network, which can offer WPT systems with various resonating frequencies. By adopting the power supply with multiple-frequency components, the power can be simultaneously transmitted to loads at corresponding frequencies while avoiding the utilization of transformer or extra transmitting coils. As a result, the proposed MFRC-based multichannel transmission scheme can effectively reduce the power loss and the complexity, as well as increase the transmission efficiency of multiple-pickup WPT systems. In this paper, simulated and experimental results are both given to verify the feasibility of the proposed MFRC network for the multichannel transmission of multiple-pickup WPT systems.

用于无线电力传输多通道传输的多频谐振补偿

本文提出了一种用于多拾波无线电力传输 (WPT) 系统的具有多个谐振频率的补偿网络，旨在建立多个通道以同时向多个负载供电。在以往的研究中，已经多次尝试通过使用多个发射线圈或变压器来传输不同频率的功率来实现多通道传输，这不可避免地导致了额外的功率损耗。虽然负载可以同时通电，但WPT系统的传输性能和可维护性都显着恶化。为了解决这个问题，本文提出并实现了多频谐振补偿 (MFRC) 网络，它可以为 WPT 系统提供各种谐振频率。采用多频分量电源，可以将电能同时传输到相应频率的负载，同时避免使用变压器或额外的传输线圈。因此，所提出的基于 MFRC 的多信道传输方案可以有效地降低功率损耗和复杂度，并提高多拾取 WPT 系统的传输效率。在本文中，给出了模拟和实验结果，以验证所提出的 MFRC 网络用于多拾音器 WPT 系统的多通道传输的可行性。所提出的基于MFRC的多信道传输方案可以有效降低功率损耗和复杂度，并提高多拾波WPT系统的传输效率。在本文中，给出了模拟和实验结果，以验证所提出的 MFRC 网络用于多拾音器 WPT 系统的多通道传输的可行性。所提出的基于MFRC的多信道传输方案可以有效降低功率损耗和复杂度，并提高多拾波WPT系统的传输效率。在本文中，给出了模拟和实验结果，以验证所提出的 MFRC 网络用于多拾音器 WPT 系统的多通道传输的可行性。
