Wireless power transfer (WPT) technology has the advantages of intelligence and facilitation. This paper designs a WPT system applied to battery charging and provides a strategy which switches from the constant current (CC) charging mode to constant voltage (CV) charging mode. The LCL-LCL topology is used to realize the CC output, while the LCL-S (series compensation) topology is used to realize the CV output. The main factor affecting the output characteristics is extracted by analyzing the two topologies above. Based on the main factor, this paper puts forward a modified way to design the system. In addition, on-line monitors for the battery and switches are placed at receiving side, which avoids the need for introducing an information interaction module into the system. Therefore, the complexity of the controlling system is reduced. Finally, simulation and experimental analyses are carried out to verify the correctness of the compound topologies.

Titanium alloy thin-plates have been widely used in the aerospace, automotive and biomedical industries, to name a few. The chipmorphologies and material properties of the thin plate were investigated under different cutting parameters in this paper. First, to furtherunderstand the variability and inherent rules of chip morphology, the characteristics of multi-surface chips (free, back, and cross-sectionsurfaces) were observed and studied by using a scanning electron microscope. The sawtooth frequency and degree of segmentation wereanalyzed through the geometrical characteristics of a serrated chip. Second, variations in the chip microhardness and the wear of the millcutter were measured and investigated under different machining parameters. Results show that the hardenability increases with the increasein cutting speed and the shear band shows higher microhardness than in other parts. In addition, the degree of insert wear decreaseswith proper cutting speed and feed. Some key conclusions and future work about high-speed milling thin-plate Ti-6Al-4V aregiven.
