  • Determination method of magnetic resonant condition for multi-device wireless power transfer systems
    Patent number: 11050301
    Abstract: Disclosed is a method of determining a magnetic resonant condition for a multi-device wireless power transfer system. A magnetic resonant condition determining method may determine a resonant condition based on a charge state, for example, a number of charging devices and a relative position between charging devices, for a multi-transmitter/receiver of a wireless power transfer system.

  • Method and system for layout optimization of secondary coil for wireless power transfer
    Patent number: 10325718
    Abstract: Disclosed is a method for optimizing a layout of a secondary coil for a wireless power transfer. The method includes reconstructing a secondary coil based on a fixed grid, corresponding to a design domain, to set a relative turn of each fixed grid and obtaining at least one or more of an electromagnetic measure and a physical measure of the secondary coil to optimize a layout of the secondary coil; applying an effective turn to the optimized layout of the secondary coil to perform post-processing; and deriving a layout of a physical coil about the secondary coil. The effective turn corresponds to a difference between the relative turns existing at a same position.
