Abstract(in English) | Maximum efficiency control by changing the secondary voltage of using a DC-DC converter was introduced. However, the control method has not been used for dynamic wireless power transfer system where coupling coefficient changes drastically. The considerations about dynamics of the transmitting circuit and coupling coefficient are necessary in dynamic wireless power transfer system. In this paper, a simple method of coupling coefficient estimation with RLS (Recursive least squares) filter and maximum efficiency control are proposed. The experimental results of dynamic maximum efficiency control are provided and they indicate the effectiveness of the proposed control in a real dynamic wireless power transfer system for EVs. |
