6 FAQs about [Solar power station high voltage and high power]
Why is high-voltage solar array a major technical challenge?
Because of the interaction of special space environment and solar array, high voltage is a huge technical challenge for the high-power solar array. Lots of studies have focused on the high-voltage solar array [ 19, 20, 21, 22, 23 ]. HORYU-II mission demonstrated the solar array over 350 V in space in 2013.
Is there a high-reliability space high-voltage converter?
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.
How to transmit high power in space?
3. New material and component are important for the high-power electric system in space. New high-conductive conductor materials, for example, graphene, are needed to decrease the weight of cables. High-temperature superconductive material over 200 K may be the best way to transmit high power in space.
What is the output voltage of a solar sub-array?
The output voltage of the solar sub-arrays is 5 kV. The voltage is boosted to 20 kV to reduce transmission loss before being transmitted to the antenna. The antenna has two main buses (multiple cables) of 20 kV and 50 kA. The third segment is the power transmission and management on the antenna.
How much power does a solar array produce?
The total output power of all 600 solar array modules of the SECC sub-system is about 2.4 GW, while the total weight is about 1800 tons. Because of the interaction of special space environment and solar array, high voltage is a huge technical challenge for the high-power solar array.
