Embodiment 1
[0013] like figure 1 As shown, it is a schematic diagram of the overall functional structure of a stratospheric aerostat power supply structure of the present invention, including a first power supply unit and a second power supply unit with the same structure.
[0014] The first power supply unit includes a first solar battery array, a first unidirectional DC converter, a first bidirectional DC converter, and a first energy storage battery, which are electrically connected in sequence. Between the first solar cell array and the first unidirectional DC converter, and between the first bidirectional DC converter and the first energy storage battery, isolating switches (switch 1, switch 8) are respectively provided for when the first When the solar battery array or the first energy storage battery fails, the isolation switch is turned off to electrically isolate the failed components. The output terminal of the first unidirectional DC converter and the left output terminal of t...
Embodiment 2
[0018] like figure 2 As shown, it is a schematic diagram of the installation structure of a stratospheric aerostat power supply structure installed on the aerostat according to the present invention. Described stratospheric aerostat comprises the buoyancy capsule body 1 that is used to provide lift, and the upper surface of described buoyancy capsule body 1 is provided with first solar cell array 11 and second solar cell array 21; The lower part is also provided with a first energy cabin 10 for installing the first unidirectional DC converter, the first bidirectional DC converter and the first energy storage battery, and for installing the second unidirectional DC converter and the second bidirectional DC converter. The second energy cabin 20 of the device and the second energy storage battery. The positions of the first energy compartment 10 and the second energy compartment 20 can be determined according to the design requirements of the center of gravity of the aerostat, ...
Embodiment 3
[0020] This embodiment provides the working state of the power supply structure of the stratospheric aerostat described in Embodiment 1 and the logic control mode of multiple switches.
[0021] 1. Normal working mode
[0022] like figure 1 As shown, when all components are fault-free, switch 3 and switch 10 are open, and the remaining switches are closed. At this time, the first power supply unit and the second power supply unit work independently and jointly provide power for the bus load. That is, the electric energy generated by the first solar battery array and the second solar battery array is transformed by the first unidirectional DC converter and the second unidirectional DC converter respectively, and then sent to the bus bar in parallel to supply power for the bus load. At the same time, the first energy storage battery and the second energy storage battery are connected in parallel with the bus bar through the first bidirectional DC converter and the second bidirec...
