title = "Power Processing Unit and Feed System Development for a Multimode Spacecraft Propulsion System",
abstract = "Multimode spacecraft propulsion systems integrate two or more propulsive modes that use a shared propellant. A multimode system combining a chemical decomposition mode with an electrospray mode is presently being developed at the University of Illinois Urbana-Champaign in collaboration with Froberg Aerospace, LLC. Fundamentally, a multimode spacecraft propulsion system consists of a thruster, power processing unit, and a propellant feed system. This paper details the ongoing development of a power processing unit and feed system for a previously developed prototype monopropellant-electrospray thruster. The power processing unit consists of two separate voltage-boosting circuits, one delivering 3.25 kV DC during electrospray operation and the other delivering 24 V DC during chemical mode operation. The feed system architecture is a single gas-pressurized system with distinct flow paths for each mode of operation and must provide volumetric flow rates of approximately 850 nL/s in electrospray mode and 100 μL/s for chemical mode operation.",
