Topic #2: Rad-Hard High-Power
Electronics
• Description of need:
o Electronic components and circuitry for space system
applications are required to work in the radiation
environment of space--testing for rad-hard is
expensive
o There is a need for standardized radiation data that
could be used to assess electronic components during
the design phase
o Current power designs are limited by a sparse
selection of high voltage diodes
• AR is seeking innovative ideas for new types of
space flight high power electronics packages that
show high tolerance to the space environment,
without incurring mass or volume penalties. For
example:
• High temperature silicon carbide (SiC) electronics is
desirable for its power handling capabilities, but there
needs to be a way to make it rad-hard
• Alternate materials and designs are sought (e.g.
gallium nitride (GAN) based solutions)
• SiC or GAN microcircuits are faster and less noisy that
Si microcircuits
o Immediate need: SiC Schottky diodes that are rad-
hard
• Target market:
o Space vehicle & electronics industry (i.e. NASA,
commercial & defense satellite/launch industry)

7. Strategic Benefits:
• While radiation hardening is
relevant to space propulsion, the
topic has applications across the
space domain. For example:
o Low-cost, rad-hard memories and
processors that are able to
operate in space
• Co-development of a novel material
or process for AR products may
lead to long-term business
•

Project Context:
• AR is the leading manufacturer of
space propulsion systems, in
particular power electronics for
electric propulsion.
• Using innovative technology to
provide our customer’s with
superior solutions is a fundamental
part of AR’s culture
Project Importance: Rad-Hard
High-Power Electronics
Aerojet Rocketdyne Startup
• AR is a producer of high power electronics for space applications, for
NASA and DoD
• An ideal startup partner should have a deep knowledge of power
electronics and radiation effects
Partnership

8. Summary
• AR development of next generation space
propulsion products leads to many exciting
development challenges
• Topics presented today
– Corrosion barrier
– Rad-hard electronics
– Obsolescence
• Many more challenges exist – Partnerships are
always welcome!
