Wireless energy transfer converters

A system comprising:

• a source resonator configured to generate a first oscillating magnetic field characterized by a first plurality of parameters,
• a device resonator configured to capture electrical energy received wirelessly through a second oscillating magnetic field characterized by a second plurality of parameters different from the first plurality of parameters;
• and
• a wireless power converter including conversion circuitry configured to capture energy from the second oscillating magnetic field and to energize the source resonator to generate the first oscillating magnetic field;
• wherein the first plurality of parameters and the second plurality of parameters of the oscillating magnetic fields are different in a least a magnitude.

A method of wireless power conversion comprising:

• providing a configurable magnetic resonator,
• tuning the configurable magnetic resonator to capture a first oscillating magnetic field characterized by a first plurality of parameters;
• converting the oscillating magnetic field into electrical energy;
• storing the electrical energy as stored energy in an energy storage element;
• tuning the configurable magnetic resonator to generate a second oscillating magnetic field characterized by a second plurality of parameters;
• and
• energizing the configurable magnetic resonator using the stored energy to produce the second oscillating magnetic field;
• wherein the first plurality of parameters include a first magnitude different from a second magnitude of the second plurality of parameters.
