Inductive battery recharging system with peak voltage detection |
摘要 |
A method is provided for inductively charging a rechargeable battery of a portable device in a vehicle via a primary circuit that includes a primary inductive coil, a secondary circuit that includes a secondary inductive coil, and a rectifying circuit electrically coupled to the rechargeable battery. A primary coil is energized with a supply voltage. A frequency of the supply voltage is varied. A peak voltage of the primary circuit is detected. The frequency of the supply voltage is adjusted to a respective frequency associated with the peak voltage. |
