A concept of a modular and scalable 10kW to 80kW High Temperature Boost (HTB) Power Processing Unit (PPU) capable of operating at temperatures beyond the standard military temperature range was proposed for solar electric in-space propulsion. Within the PPU, the Anode Power Supply (APS) module is a 10kW modular power stage and is the key to the HTB PPU. This paper is to present the design, development,...
The power processing unit (PPU) of a solar electrical propulsion system for in-space propulsion is developed as a high power, temperature, and efficiency, modular, high specific impulse, and non-isolated converter topology unit for future deep space and manned missions. Overall, the High Temperature Boost (HTB) PPU has 87% improvement in PPU specific power/mass and 38% improvement in-space solar electric...
