Title
(EN) Unmanned aerial vehicle power supply system
(ZH) 一种无人机供电系统
Abstract
(EN)
The invention discloses an unmanned aerial vehicle power supply system comprising a main power source, a secondary power source, and an auxiliary power source, which are connected in sequence. The main power source comprises an electronic control unit ECU, an engine, a generator, a controller, a throttle, a rectifier unit, an encoder, and a filter unit. The secondary power source comprises an intelligent charging unit and a constant voltage unit. The filter unit in the main power source is connected with the intelligent charging unit and the constant voltage unit. The auxiliary power source comprises a storage battery which is connected with the intelligent charging unit. The unmanned aerial vehicle power supply system can power various unmanned aerial vehicles, and is applicable to multi-rotor aircrafts, helicopter aircrafts and tilting rotor machines. The power can be set according to actual needs. The unmanned aerial vehicle power supply system is convenient, flexible and highly technological, and meets the power supply demands of all kinds of large-load and long-flight unmanned aerial vehicles.
