Space Power Satellite (SPS) is a huge spacecraft to utilize solar energy in space. Because of the huge size, immense mass and high power, there exist many technical difficulties. For a GW SPS system, the generated electric power in space will be over 2 GW, and the whole area of the solar array will be several square kilometers. The high-power electricity
The power supply plays an important role in the space welding applications, while there isn''t such a high-voltage power design. For space solar power station, as an ultra-high-power space system, they require the transmission of electricity over hundreds of kilometers (Xin-bin and Li, 2015; Zaitsev et al., 2019). In order to minimize losses
Deep space exploration missions, also based on the more intensive use of Electrical Propulsion, require very high quality power solar array using high voltage bus (above 300V) enabling direct driving by the solar array and minimizing the operating current.

This special issue is dedicated to the field of Space Solar Power Station (SSPS). Proposed by the American scientist Peter Glaser, SSPS is a grand idea to build an extra-large solar power station on the Earth orbit and to transmit electricity to the surface ground wirelessly, such as through microwaves.
Aiming at this situation, this paper proposes a high-reliability space high-voltage converter. Based on the experiments, we take the phase-shifted full bridge series resonance circuit to optimize the efficiency of the high-voltage converter, the optimization results and electric field of the experimental circuit board are simulated and verified.
The proposed Modular Demonstrated Space Power Station (MD-SPS) is shown in Fig. 3. The MW-level MD-SPS adopts 3D folded truss and I-shaped structure as the main load bearing structure to make the load-bearing structure be the full truss.
At the module level, the integration of microwave energy conversion and emission and the collaborative design of mechanical, electrical and thermal dimensions are solved integratedly, which enables high-integration antenna modules and greatly reduces the weight of the antenna array surface.
