Design of Dual Frequency Class E Resonant Converters for Simultaneous Wireless Power and Data Transfer in Low Power Applications
Wireless power transfer (WPT) applications frequently use resonant converters that operate at high frequencies. For consumer electronics charging systems to effectively use WPT, both power and data transfer must occur over the same inductive link. This work proposes a novel approach for creating Cla...

| description | Wireless power transfer (WPT) applications frequently use resonant converters that operate at high frequencies. For consumer electronics charging systems to effectively use WPT, both power and data transfer must occur over the same inductive link. This work proposes a novel approach for creating Class E resonant converters that can function at two frequencies, allowing the source and the load to transfer power and data simultaneously. Resonant converter performance can be negatively impacted by fluctuations in load and coupling between the coils, which are typical in real-time applications. A dual-frequency load impedance network is made to match variations in load at both resonant frequencies. In addition to analyzing the performance of the converter with a dual-frequency impedance matching circuit, mathematical design and analysis are carried out at different duty ratios. With dynamic load conditions, the suggested design achieves zero derivative switching (ZDS) and zero voltage switching (ZVS), demonstrating superior performance at both frequencies. The proposed converter operates simultaneously at two resonant frequencies, achieving a high power transfer efficiency of 91.3 %, with the original design resonant frequency set at 1 MHz. ? 2024 The Author(s) |
