Abstract
A system including a primary coil assembly is provided. The primary coil assembly is configured to operate at a first resonant frequency having a first bandwidth; wherein a difference between the first resonant frequency and a system frequency is at least two times the first bandwidth, where the first resonant frequency is selected such that upon energizing the primary coil assembly at the system frequency, a primary current is induced in the primary coil assembly, which is at least ten times lesser than a system current.
Claims20
A system comprising:
- a primary coil assembly configured to operate at a first resonant frequency having a first bandwidth;
- wherein a difference between the first resonant frequency and a system frequency is at least two times the first bandwidth;
- wherein the first resonant frequency is selected such that upon energizing the primary coil assembly at the system frequency, a primary current is induced in the primary coil assembly, which is at least ten times lesser than a system current.
A wireless charging system comprising:
- a power source configured to operate at a system frequency;
- a wireless charging device operatively coupled to the power source comprising:
- one or more resonator coils configured to operate at a first resonant frequency and having a first bandwidth;
- wherein a difference between the first resonant frequency and a system frequency is at least two times the first bandwidth;
- wherein the first resonant frequency is selected such that upon energizing the one or more resonator coils by the power source at the system frequency, a primary current is induced in the one or more resonator coils, which is at least ten times lesser than a system current.
- one or more electrical devices comprising:
- one or more load coils operatively coupled to a load in respective electrical devices;
- wherein upon magnetically coupling the one or more load coils to the one or more resonator coils, the system current is induced in the one or more resonator coils to enable exchange of power between the one or more load coils and the one or more resonator coils.
