A high power high voltage dc/dc converter for space applications
Abstract
The design details of a modular dc/dc converter used to power the main anode supply of a mercury ion motor are presented. This motor, the RIT-35 built by M.B.B. Germany, is used as the propulsion unit of a future Asteroid Gravity Optical and Radar Analysis (AGORA) mission. This paper shows the design selected to cope with the high voltage, high power conversion for space applications and the requirement to operate from an unregulated solar array with a voltage excursion of from 150 volts beginning-of-mission (BOM) to 240 volts end-of-mission (EOM).
