The invention provides a power supply circuit, device and system of an uninterruptible power supply. An uninterruptible control circuit 4 is additionally arranged between a storage battery 20 and an uninterruptible power supply bus bar 3, and when a main generator 30 works normally, the access between the storage battery 20 and the uninterruptible power supply bus bar 3 is disconnected through the uninterruptible control circuit 4, and the purpose of not consuming the electric quantity of the storage battery is achieved so that the emergency power supply time of the storage battery is prolonged. Only when the main generator 30 is in an abnormal working state, the access of the storage battery 20 and the uninterruptible power supply bus bar 3 is conducted through the uninterruptible control circuit 4 so that when the main generator 30 fails, the storage battery 20 can be controlled to be connected, and uninterruptible power supply is ensured. 本发明提供了一种不间断电源的供电电路、装置及系统，本发明提供了一种不间断电源的供电电路、装置及系统，在蓄电池20与不间断供电汇流条3之间
