This document is a NASA Shared Services Center Recommendation and Determination to Solicit from One Source for Wolfspeed 300 kW 3-phase power inverters. The document justifies a sole source procurement for five power inverters (CRD300DA12E-XM3) with a total estimated cost of $46,875 and an estimated lead-time of less than two weeks from order receipt. The recommendation is based on unique technical requirements specific to the D Site test facility at NASA's Armstrong Test Facility, where these inverters are critical for conducting electrified aircraft propulsion research.

The document provides detailed rationale for selecting Wolfspeed as the sole source, highlighting that their inverters are the only ones that can fully interface and permit precise control of test bed motors, with proprietary algorithms that cannot be replicated by other vendors. NASA researchers have determined that switching to another inverter brand would waste government resources and prevent obtaining the specific data control required for their research. The procurement is set aside for small businesses, and all vendors are advised to reference the solicitation number 80NSSC25907132Q in their correspondence.
