A Novel Conception of SWIPT System Considering Information Independent Transmission

In the conventional structure of simultaneous wireless information and power transfer (SWIPT) system, the information channel depends on power transmission, which means if there is no power transfer, then all switches in the inverter are turned off, it is impossible to transfer information anymore. Therefore, an improved structure of SWIPT system with independent information channel is proposed in this paper. This paper establishes the model of the structure and analyzes the power and information channel of the system to verify the feasibility of the structure. Theoretical analysis and simulation results validate the proposed conception of information transmission with an independent channel.
