Problems solved by technology

During the take-off, cruising, and landing phases of the UAV, the incident angle and temperature of the sun will change greatly, which will easily cause the working point of the solar cell array to drift. In addition, the voltage of the battery is low during the charging stage, which will clamp the solar cell array. , in order to make better use of the energy emitted by the solar array, it is necessary to adopt an appropriate way to manage the energy system

Abstract

The invention discloses a distributed energy source system used for a solar unmanned aerial vehicle. The system is characterized by at least comprising a plurality of photovoltaic modules, a power optimizer electrically connected to each photovoltaic module, a high-voltage bus of 80V-120V and a low-voltage bus of 27V-29V, wherein each power optimizer comprises an MPPT controller and a DC-DC converter; an output terminal of each photovoltaic module is electrically connected to an input terminal of one DC-DC converter; a transmission conductor between the photovoltaic module and the DC-DC converter module is connected to the MPPT controller; after connected in series in sequence, the DC-DC converters are connected to the high-voltage bus of 80V-120V; after connected in series in sequence, the DC-DC converters are connected to a lithium ion battery series; and after connected in series in sequence, the DC-DC converters are connected to the low-voltage bus through one DC-DC converter. According to the system, the conversion efficiency of the photovoltaic modules can be improved.

Description

technical field [0001] The invention relates to the technical field of power supply control for space vehicles, in particular to a distributed energy system for solar-powered drones. Background technique [0002] The solar-powered unmanned aircraft has long cruising time, high flying altitude, wide coverage area, and can perform a variety of tasks, which has irreplaceable advantages of conventional aircraft. The solar unmanned aircraft energy system uses photovoltaic conversion to convert solar radiation energy into electrical energy, providing long-term power energy for unmanned aerial vehicles. The power generation of the solar cell array is very uneven within a day, and a suitable power control method is very necessary. During the take-off, cruising, and landing phases of the UAV, the incident angle and temperature of the sun will change greatly, which will easily cause the working point of the solar cell array to drift. In addition, the voltage of the battery is low dur...
