Abstract

The invention discloses a starting and generating integrated system for the oil-electricity hybrid unmanned aerial vehicle and the control method. The system comprise an engine, a starting generator and a bidirectional PWM rectifying circuit connected with the unmanned aerial vehicle, the engine is connected with the starting generator, the starting generator is connected with the bidirectional PWM rectifying circuit, and the bidirectional PWM rectifying circuit is further connected with a battery and a controller. The bidirectional PWM rectifying circuit is adopted, the power converter and the electric generator inductor are efficiently utilized, under the condition that other functional modules are not added, starting control of the engine and rectification and voltage stabilization control of the generator are realized, so that more fuel can be carried by the oil-electricity hybrid unmanned aerial vehicle, and the endurance time of the unmanned aerial vehicle is greatly improved.

Description

technical field [0001] This patent relates to the technical field of unmanned aerial vehicles, in particular to an integrated system and control method for starting and generating electricity for an oil-electric hybrid unmanned aerial vehicle. Background technique [0002] Gasoline-electric hybrid UAVs are getting more and more attention in the application of industrial UAVs. The core technology of the oil-electric hybrid UAV is a power generation system composed of an engine and a starter generator. The starter generator power conversion circuit system of the engine on the existing oil-electric hybrid UAV is too cumbersome, and when it is applied to the UAV, the power supply performance is greatly reduced. [0003] For example, if the ground starter is used to start, and then the generator set supplies power, the flexibility will be reduced; if the output power supply scheme is not controlled rectification plus DCDC voltage regulator circuit, there are too many links, whic...
