Modeling of WPT System for Small Home Appliances

Wireless Power Transfer (WPT) is a developing technology that increases user benefits in various areas. In this study, the system parameters of WPT technology for small home appliances were examined. Accordingly, computer-aided modeling studies of the coil and electronic circuit structure that enable the wireless transmission of energy with WPT have been carried out. ANSYS Maxwell 3D and Simplorer have been used for coil analysis and electronic circuit simulation, respectively. To shorten the simulation time for the coil analysis, a simplified coil design has been proposed. Variables such as air gap and operating frequency, which are very critical for energy transfer, have been parameterized through this model. Coil and system efficiency can be calculated with the dynamic WPT model obtained, the results are compared with the real system.
