Abstract
The invention discloses a low-power UPS, and relates to the technical field of the uninterruptible power supply (UPS). The low-power UPS comprises a storage battery, a charging unit, an inversion unit, a transformer for voltage stabilization, and an output unit which is used for outputting outwardly, wherein when the low-power UPS works in a mains supply mode, the charging unit takes power from the mains supply to charge the storage battery; the transformer takes power from the mains supply, performs voltage stabilization and then outputs the power to the output unit; the transformer is an autotransformer; the low-power UPS also comprises a DC/DC conversion unit; when the low-power UPS works in a battery mode, the electric energy output by the storage battery is subjected to voltage conversion by the DC/DC conversion unit, and then the electric energy is output to the inversion unit; and next, the electric energy is inverted into alternating current by the inversion unit, and finally the alternating current is output to the output unit.
