Key Details
Official Description
Historically, U.S. space dominance relied on a benign environment where assets operated statically to provide communication, intelligence, surveillance, reconnaissance (ISR), and positioning, navigation, and timing (PNT) functions. Today, space is a contested and active warfighting domain. In response, the U.S. Space Force (USSF) is adopting the "Maneuver Without Regret" (MWR) concept. Implementing MWR necessitates high-voltage architectures (200V–800V) to support next-generation Electric Propul...
Change History
Power the space: high-voltage radiation hardened power switches for space power and propulsion
Added 1 new Q&A (Q1) clarifying scope: topic targets radiation-hard high-power switching devices (MOSFETs, GaNFETs) but may extend to broader high-power, high-voltage rad-hard converter systems. Previous Q&As renumbered accordingly.
Power the space: high-voltage radiation hardened power switches for space power and propulsion
Q1 and Q2 received new answers. A1 clarifies feasibility documentation can rely on TCAD simulations, preliminary testing, manufacturability evidence, and packaging assessments—no fabricated/tested device required. A2 confirms minimum requirement is radiation immunity at Vds ≥600V; 1kV operation is preferred, not mandatory.
Power the space: high-voltage radiation hardened power switches for space power and propulsion
Added 2 new Q&As: Q1 clarifies that Phase I feasibility can be demonstrated via TCAD simulation, foundry compatibility, and plans without requiring fabricated/tested devices at proposal submission. Q2 clarifies that SEB immunity demonstration above 600V satisfies the minimum requirement, with 1 kV operation preferred but not mandatory.
Power the space: high-voltage radiation hardened power switches for space power and propulsion
Q1 received an answer clarifying that the project is open to all material systems and device topologies, not limited to specific technologies like SiC or Si MOSFETs.
Power the space: high-voltage radiation hardened power switches for space power and propulsion
This Q&A clarifies a critical technical scope issue: applicants must confirm whether the project targets Silicon Carbide (SiC) MOSFETs or traditional Silicon MOSFETs, as the technology platform fundamentally determines feasibility and approach for improving secondary breakdown (SEB/SEM) performance.
