Considerations for Mechanical Fixturing and Mass Augmentation of Piezoelectric Resonators in DC-DC Power Converters
This work explores the implications of mounting and fixturing of piezoelectric resonators (PRs) for applications in inductorless DC-DC power conversion. From a scalability and packaging perspective, various mounting strategies are evaluated, and impacts of solder bonding of PRs on performance and losses are quantified. COMSOL simulations are performed to verify shifts in PR resonance. Insights from fixturing are applied to assess the impact of mass augmentation strategies on mechanical losses and understand the feasibility of achieving higher power densities. Fixtured and augmented PRs are subsequently evaluated in a DC-DC converter to test the influence on converter efficiency.
