1. A method of extracting power, comprising the steps of:

  • coupling a transducer that converts mechanical power to electrical power to a disturbance, coupling an electrical circuit to the transducer such that a peak voltage experienced by the transducer is greater than two times higher than any peak voltage of an open circuit transducer due to the disturbance alone, wherein coupling the electrical circuit includes controlling switches electrically connected to the transducer, extracting power from the transducer using the electrical circuit, and storing extracted power.
