Within this paper we present the design and implementation of a modular commercial off the shelf (COTS)-
based brush less direct current (BLDC) power stage using gallium
nitride - field effect transistors (GaN-FETs). Possible application
scenarios are small mobile systems for lunar application with
short and medium envisaged mission lifetime. We are giving
insight in the design process of the power stage and component selection process.
Furthermore, mitigation techniques for
radiation environment, redundancy and special electrical design
considerations are covered. Detailed insights in development,
design, and production of the power stage, are presented and
next steps for technology readiness level (TRL) increase. The
described results are based on the DFKI's outcome of the project
iCOTS which ended in July 2023.
