Abstract

Previous efforts to develop power processing units (PPUs) for Hall thruster systems were targeted for the 1- to 5-kW power range and an output voltage of approximately 300 V. The NASA Glenn Research Center is developing new high-power Hall thrusters with a favorable combination of thrust, specific impulse, and efficiency to enable Earth-orbiting and Mars missions. These thrusters require up to 100 kW of power and a discharge voltage in excess of 800 V.
