specific example

[0031] See figure 1 , The electrical system is composed of motors, motor drive controllers, solar cells, MPPT, batteries, DC-DC, power buses, equipment buses, electrical control devices, and electrical equipment. With the application of the invention, the electrical system architecture of the solar UAV can be designed. The electrical system is designed by motor and DC-DC according to the coordination method between equipment weight and redundant backup.

[0032] Preferably, the motor Ⅰ (1) and motor Ⅱ (2) have the same structure and are respectively driven and controlled by the motor drive controllers MC Ⅰ (3) and MC Ⅱ (4). The sum of the power of the two is greater than or equal to the maximum required by the UAV propeller Mechanical power value, the two are coaxially connected, and output the same torque when working. When one of the motors fails, the other can ensure that the drone has a certain amount of power to return home. At the same time, the weight of the drone is not...

Abstract

The embodiment of the invention discloses a solar unmanned aerial vehicle electrical system, which relates to a solar unmanned aerial vehicle electrical technology and can solve the problems that theexisting solar unmanned aerial vehicle electrical system is complicated in design process and low in reliability. The system comprises a power bus and a device bus which are in parallel, wherein the device bus is used for connecting a power consumption device; the power bus is used for connecting the other device except the power consumption device; multiple DC / DC converters connected in parallelwith each other are connected between the device bus and the power bus; and the power bus is connected with a solar cell, a first motor and a corresponding first driving controller MC, a second motorand a corresponding second driving controller MC, multiple solar cells and MPPTs corresponding to the solar cells.

Description

Technical field [0001] The invention relates to the technical field of solar unmanned aerial vehicle electrical technology, in particular to a solar unmanned aerial vehicle electrical system. Background technique [0002] As an important system of solar-powered drones, the electrical system is designed to affect the overall performance of the drone. The electrical energy of the solar-powered drone comes from solar cells and energy storage batteries, and the generation, transformation and transmission of electrical energy are realized by electrical devices on the aircraft. Existing solar-powered drones mostly use distributed power systems, that is, multiple drive motors are distributed on the wings. This kind of structure is a flexible structure, and there are unresolved problems in aerodynamic performance. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a solar unmanned aerial vehicle electrical s...
