Abstract:
A system to recharge a battery including a first current-voltage source to generate a first signal, a second current-voltage source to generate a second signal, a first inductor-capacitor circuit to generate the first DC current-voltage signal using the first signal, a second inductor-capacitor circuit to generate the second DC current-voltage signal using the second signal, wherein the first and second inductor-capacitor circuits are spaced apart by a predetermined distance. The system also includes a temperature sensor adapted to generate temperature data during the charging operation, and control circuitry configured to: (i) determine whether the first temperature data is out-of-specification, and (ii) generate one or more control signals to adjust the first and second DC current-voltage signals, in response to the first temperature data being out-of-specification.
