Wireless Power Transfer
Wireless Power Transfer is now being watched with interest by many electronics engineers who understand challenges such as usability and safety in designing charging technology. While this new technology started with smaller mobile devices such as cell phones and laptop PCs, it is now being applied in the area of automotive EV (electric vehicle) charging systems which require larger power capacities in a very limited space. The key component in the technology is a loosely coupled transformer needing coupled electromagnetic field analysis and circuit simulation for its design. ANSYS products provide an intuitive solution which characterize the efficiency of these devices. This presentation introduces wireless power transfer simulation using Maxwell and Simplorer including a specific example of the magnetic resonance type.
