The invention relates to a dual-redundancy uninterruptible power supply control circuit for an unmanned aerial vehicle, and solves the problems of a current power supply mode. Comprising a main generator, a storage battery, an uninterruptible control circuit and an uninterruptible power supply bus bar, the uninterruptible control circuit comprises an uninterruptible circuit I, an uninterruptible circuit II, a current detection circuit, a control protection circuit and a grid-connected relay, and when the main generator breaks down and the voltage of the uninterruptible power supply bus bar is lower than a rated value, the two uninterruptible circuits work at the same time; a double-redundancy circuit is formed, a storage battery power supply is led to an uninterrupted power supply bus bar, the two uninterrupted circuits are controlled by a power triode to be switched on and switched off, and when the circuits work for a long time, the heat productivity of the triode is large, and the current detected by a current detection circuit is larger than a certain value, a control protection circuit controls a grid-connected relay to be switched on. And the continuous maintenance is completed by a grid-connected relay. The reliability of uninterrupted power supply is improved, the emergency power supply time is prolonged, and the service life of the storage battery is prolonged.
本发明涉及一种无人机双余度不间断供电控制电路,解决了目前供电方式存在的问题。包括主发电机、蓄电池、不间断控制电路和不间断供电汇流条,不间断控制电路包括不间断电路I、不间断电路II、电流检测电路、控制保护电路和并网继电器,当主发电机故障,不间断供电汇流条电压低于额定值时,两个不间断电路同时工作,形成双余度电路,将蓄电池电源引向不间断供电汇流条,两个不间断电路均由功率三极管控制通断,当电路长时间工作,三极管本身发热量较大,当电流检测电路所测的电流大于一定值时,控制保护电路控制并网继电器闭合,不间断保持由并网继电器完成。本发明提高了不间断供电的可靠性和应急供电时间,延长了蓄电池的使用寿命。
