Abstract The wireless power transfer (WPT) has been receiving a considerable amount of interest. In this paper, we aim to design a universal WPT desktop which can provide power for a variety of WPT device. We defined that its power supply system should be simple, small size and higher power. For this purpose, the complex DC power supply is replaced by using Utility power directly and Main circuit structure is simplified by using the single-switch parallel resonant topo structure. The detailed Transient processes of operation mode of the system are analyzed and then Safety operation condition of the system is proposed. Design and analysis of the system includes both primary and secondary side. It is verified by numerical simulation using MATLAB and the real experiment using the prototype of the WPT desktop with a LED table lamp supplied by the desktop.
