High Power Density DC-DC Piezo-Converter module for Small Satellites

Face Electronics, LC proposes to design an innovative high power density, radiation-resistant, space-qualified, DC-DC converter module using Face's proprietary technology. This technology includes a new high power density piezoelectric transformer, Transoner?, which is designed to replace the conventional magnetic technology. Transoner is smaller, weighs less and significantly reduces magnetic interferences, as is required for small satellite applications. The novel DC-DC Piezo-Converter is proposed as an alternative to the current DC-DC converter modules used to drive satellite payloads. In order to demonstrate the feasibility and benefits of this innovation, Phase I will be focused on the preparation of two DC-DC converter modules to demonstrate the step-up and step-down capabilities and thus the potential standardization of the technology. The step-down demonstrator will be a 15W DC-DC converter from 28V input to 5V output. The step-up demonstrator will be a 15W DC-DC converter from 28V to 100V output. Results of the Phase I will quantitatively validate the design feasibility, and provide the basis for refinement, miniaturization and packaging in Phase II to standardize the novel DC-DC concept to the requirements of nanosatellites.
