New Electrical Power Supply System for All-Electric Propulsion Spacecraft

This paper proposes a novel electrical power supply system architecture (power conditioning and processing unit, PCPU) for high-power all-electric propulsion spacecraft platform with high-voltage power bus (HVBUS) powering thrusters and regulated power bus (VBUS) powering onboard payloads, respectively. The design principle of function modules in PCPU has been analyzed. Besides, the test on electrical characteristic of VBUS and HVBUS in prototyped system proves the stable and reliable work of buses in PCPU.
