Abstract

In this paper, a novel method to characterize and measure the small-signal stability margin of spacecraft power systems is proposed with the aim of addressing the problem that the current stability margin standard fails to meet the requirements for development of aerospace power technology. A delay margin and a modulus margin are added to the current small-signal stability margin standard for space power systems. The new generalized characterization method reflects the system's robustness fully and provides more strict characterization of the stability of the spacecraft power system. In this work, three types of spacecraft power supplies are measured using the proposed stability margin measurement method based on the frequency response curve. Comparison of the measurement results with the results of the theoretical analysis verifies the feasibility of the measurement scheme. Finally, a recommended range is proposed for the stability margin and the stability one type of power supply is analyzed to provide further theoretical support for stability analysis of spacecraft power systems.
