Brief description of the drawings
Fig. 1 is the operation principle block diagram of uninterrupted power supply in the present invention.
Embodiment
Below against accompanying drawing, by the description to embodiment, for example involved each component of embodiment of the invention
Shape, construction, the mutual alignment and annexation between each several part, the effect of each several part and operation principle, manufacturing process and
Operate with method etc., is described in further detail, to help those skilled in the art to inventive concept of the invention, technology
Scheme has more complete, accurate and deep understanding.
A kind of uninterruptible power system, as shown in figure 1, the power supply in the present invention includes alternating current and direct current, alternating current
For traditional industrial frequency AC, alternating-current switch power module connection AC power, reaches and can make so as to adjust alternating current in alternating current
Purpose, direct current electrical connection is transported to secondary device/monitoring system.Direct current is the high pressure provided using high-tension battery group
