Topology and Control Method of Z-Source-Based Lunar Flexible Power Transmission System

Lunar microgrid technology is the key technology for providing power supply to International Lunar Research Station (ILRS). This paper addresses the long-distance electric energy transmission demand in the lunar power system by studying the topology and control method of high-efficiency converters from low-voltage direct current to high-voltage alternating current. A flexible electric energy transmission system based on Z source is proposed, utilizing a single-stage electric energy conversion topology structure. Compared to the traditional two-stage solution of DC boost followed by inversion, this approach can improve operational efficiency and reduce equipment costs. Additionally, modulation and control method for the proposed scheme are studied, providing theoretical and engineering references for the construction of the power supply system for ILRS.
