Abstract: Described are structures and techniques for providing high-efficiency, high-power-density piezoelectric resonators (PRs) for use in power converters. In some embodiments, a power converter can include a PR for energy transfer, where the PR substantially satisfies geometry conditions disclosed herein for achieving high-efficiency and high-power-density. The geometry conditions can be defined in terms of the converter's specified (e.g., rated) voltage and power level.
