The wireless power transfer (WPT) technology has the advantages of convenience, safety\nand reliability due to its non-metal contact power supply and has a broad application prospect in\nmany occasions. In practical applications, the information communication between the primary and\nsecondary side is necessary for output voltage control, load detection, condition monitoring and\nother functions, which makes the WPT system more intelligent and convenient. A simultaneous\nwireless information and power transfer (SWIPT) system with controlled chopper circuit receiver is\nproposed in this paper. The load voltage remains constant by adjusting the pulse width of the\nsecondary controlled device through feedback control. The information bidirectional transmission\nmethods and two modes are proposed, considering different application scenarios. Simulation and\nexperiment results validate the proposed topology and the method of information bidirectional\ntransmission.
