| Abstract(in English) | This paper describes the optimum magnetic field resonance type wireless power transmission system to the charging of the lithium ion rechargeable battery. Lithium-ion batteries can suppress charge deterioration by optimizing the charging control. However, since the switching of the charging current is required, load variation of the charger may occur. Further, in the magnetic field resonance type wireless power transmission, when the load resistance is not the optimal value, the output power, and transmission efficiency decreases. Therefore, if you want to achieve the best charged by wireless power transmission of the magnetic field resonance type, optimization and charge optimization of the transmission characteristic becomes a trade-off. In the proposed system, and adjust the input voltage by the DC-DC converter of the primary side, by indirectly optimize the duty ratio of the DC-DC converter on the secondary side, load fluctuation wireless power transmission according to the optimal charging to mitigate the impact on the road. |
