Intelligent COTS based Power Stages for Robotic Applications

The objective of this project is to demonstrate a modular breadboard multi-PCB design using COTS components for space applications. The concrete demonstrator will be a COTS GaN-FET power stage of a robotic actuator. The functionality will be distributed over multiple PCBs (Processing /Sensor / Interfaces PCB, Power stage etc.). A modular approach will allow Plug and-Play reconfiguration during development. It allows the exchange of functionally equivalent modules to evaluate other implementations of a board or components. Furthermore, this enables sub-module qualification. In comparison to black box testing of monolithic PCB designs versus extensive part level qualification, this provides a satisfactory compromise in the R&D domain.
