The European Power Standard, used when designing and implementing spacecraft power buses, imposes stringent impedance requirements for high reliability and robustness, unlike other standards such as those from the American Institute for Aeronautics and Astronautics, SAE International, or the International Deep Space Interoperability Standard. These strict requirements, however, may limit innovations leveraging new technologies resulting from recent component advancements. This work examines the implications of the European Power Standard’s output impedance criteria for stability and its impact on payload power supplies, focusing on the potential to increase operational frequencies in power supply topologies to reduce system volume and mass, which are key factors in space technology.
