Abstract

The invention discloses a DC uninterrupted power source based on a cell and and a super capacitor. The DC uninterrupted power source based on the cell and and the super capacitor comprises a rectification circuit, a DC / DC voltage stabilizing unit, a cell charging / discharging circuit, a super capacitor charging / discharging circuit and two voltage stabilizing capacitors. The DC power source employs a method combining the super capacitor and the standby power source, when AC input is normal, the cell and the super capacitor are for charging; when AC input is abnormal, the super capacitor discharges within the cell discharging switching time, so seamless switching of the standby power source is guaranteed, the DC uninterrupted power source is suitable for occasions having strict power source requirements, the DC uninterrupted power source can further adapt to different input voltages, the DC uninterrupted power source further has advantages of relatively small volume, small part quantity and relatively low manufacturing cost, and the DC uninterrupted power source is suitable for popularization and application.

Description

technical field [0001] The invention relates to a DC uninterruptible power supply, in particular to a DC uninterruptible power supply based on batteries and supercapacitors, which belongs to the field of electronic technology. Background technique [0002] With the continuous advancement of science and technology, electrical engineering and automation technology are developing at an impressive speed, changing the overall appearance of my country's industry. Among them, precision electronic instruments and equipment have higher and higher requirements for power supply quality. In various power supply methods, in addition to providing high-quality power supply, uninterruptible power supply can also ensure that the power supply will not be interrupted, so uninterruptible power supply has become an optimal solution for supplying high-quality power supply. [0003] The traditional backup power supply requires a certain switching time before it can supply power to the load, and ca...
