Abstract – Present electric propulsion power processing unit (PPU) technology represent a major cost element in modern spacecraft electric propulsion systems. This is especially so because each spacecraft tends to have its own unique power bus. This suggests that a more versatile design architecture could be adopted that would allow greater spacecraft to spacecraft portability. This could provide a significant advantage in system development time, qualification, and ultimately cost savings. This also represents an excellent opportunity to explore advanced architectures and serve as a way to attract students to the aerospace power electronics profession. Michigan and consultant Battel Engineering, Inc. are proposing to collaborate with our industrial partners and others to address these issues.

PPU’s for Next Generation EP
• PPU architecture is highly customized and often specific for each mission and spacecraft– Can a more modular
approach be explored?– Can new architectures be
explored via the I-UCRC?• Attracting students to power
electronic systems is always a challenge– Can the I-UCRC help?
