UPS (uninterrupted power supply) device with low power consumption

Abstract

The invention relates to a UPS (uninterrupted power supply) device with low power consumption, which comprises an energy storage unit, an AC-DC conversion circuit, a charging circuit, a selective circuit, a main detecting circuit, a main control circuit and a minor control circuit. As the running of the UPS device is controlled by the main control circuit or the minor control circuit, the UPS device can start and stop the running of the man control circuit or the minor control circuit in good time according to running information (for example, output current) of the UPS device so as to increase the overall efficiency of the UPS device and prolong the power supplying time; moreover, the UPS device can also stop a relatively high-drain controller in good time without affecting the running and power supplying of the UPS device.

Description

technical field [0001] The present invention relates to a power supply, in particular to an uninterruptible power supply (Uninterruptible Power Supply, UPS) with low power consumption. Background technique [0002] With the rapid development of information industry and high-tech industry, most precision electronic instruments and equipment need to rely on high-quality power supply to maintain normal operation. Among various power supply methods, the UPS can not only ensure that the power supply will not be interrupted, but also provide high-quality power, so the UPS has become the best solution for providing high-quality power today. [0003] Usually, some important equipment will be powered by uninterruptible power supply to prevent important equipment from stopping due to abnormal or interruption of mains power. When using traditional uninterruptible power supply to supply power to these important equipment, uninterruptible power supply At the same time, it will continue ...

AI Technical Summary

Problems solved by technology

[0005] It can be seen that, in addition to continuously providing uninterrupted power to important equipment, traditional uninterruptible power supplies will add additional detection circuits to continuously provide additional related advanced functions, but when the equipment is not running (that is, not power consumption), these additional detection circuits and relatively high power consumption controllers will continue to run to continuously provide all related advanced functions, resulting in additional power consumption of traditional uninterruptible power supplies, which will reduce overall performance and power supply time
