| Research Abstract |
Electromagnetic resonance coupling is a new wireless power transfer technology. This technology is highly dependent on load values and fast control technique is required. Typically, control is implemented by switching condensers with different values. However the mechanical switches used have slow response. Therefore, a fast control of power electronics circuit for impedance matching is needed. The method combines power electronics and magnetic resonance coupling. The establishments of three areas are proposed in this research. (1) Impedance matching using power electronics circuit: in this study, fast control technique with power electronics is used to prevent efficiencydrop due to load value change. (2) Estimation method: estimating the load values from transmitting side. (3) Power division: controllable power division regardless of the number of receiver.
