High Power Wireless Transfer : For Charging High Power Batteries
- Publisher: Metropolia Ammattikorkeakoulu
Wireless power transfer (WPT) is developing with emerging of new technologies that has made it possible to transfer electricity over certain distances without any physical contact, offering significant benefits to modern automation systems, medical applications, consumer electronic, and especially in electric vehicle systems.
The goal of this study is to provide a brief review of existing compensation topologies for the loosely coupled transformer.
The technique used to simulate a contactless power transfer system is based on Finite Element Method or Analysis (FEM or FEA) coupled with electric circuits provided by COMSOL Multi-Physics simulation software. The task was to provide an innovative technique for high power wireless transfer with a power output ranging from 15 to 20 [kW]. Analyses were conducted with the input of zero phase angle of the supply voltage. A passive resonant network used to achieve constant (load-dependent) voltage or current output was summarized. Furthermore a simple circuit model was also simulated using National Instruments Multisim software to analyse the results.
Overall the results generated by the simulation software were at par with what was anticipated after building a mathematical model based on numerical calculations. Anyhow we were not able to build a physical working model but using the software various models were simulated with different parameters before reaching a conclusion.
