Electronic Load Evaluation for Aerospace Power System Verification

Category: Space Systems & Technology, Power & Propulsion, Tech Transfer

ABSTRACT

The evaluation and verification of Electric Power System performance requires rigorous testing for Aerospace systems. Tests to characterize this performance have typically used a mix of actual, resistive, and/or representative loads throughout the system. Use of electronic loads as a form of representative loads has typically been avoided in many scenarios because electronic loads themselves may influence and invalidate test data. As Aerospace systems scale in size, power, complexity, and cost however, it is critical to obtain a deep understanding of the limitations of electronic load use in power system testing. Once this is accomplished, electronic load use can be evaluated and enabled moving forward for considerable cost and schedule savings. This presentation seeks to highlight cases and rules of thumb where electronic loads may and may-not be used. Test data obtained from NASA Glenn Research Center Test Beds will be provided to validate findings.
