Abstract
A circuit for harvesting electrical energy from a piezoelectric source and for storing the electrical energy in a battery includes an inductor that is configured to store electrical energy. A diode bridge-free switching network is configured to: direct electrical energy from the piezoelectric source to the inductor during a first portion of a piezoelectric charge generating cycle; and direct electrical energy from the inductor to the battery during a second portion of the piezoelectric charge generating cycle.
