    The UPS technical glossary

    May , 23 2023
    This ups technical glossary is designed to help you to understand the technical terms used within the uninterruptible power supply (UPS) industry. A AC ripple Is the residual periodic variation of the DC voltage withina UPS which has been derived from an unwelcome alternating (AC) source. An AC ripple causes internal heating and deterioration of the UPS battery poles and so should be prevented fom...

    Basic knowledge of filters

    Jun , 21 2023
    The Line filter is a filter circuit composed of capacitance, inductance and resistance. A filter can effectively filter out a specific frequency point in the power line or frequencies outside of that frequency point, obtaining a specific frequency power signal or eliminating a specific frequency power signal. A filter, as the name suggests, is a device that filters waves. Wave "is a very broad phy...

    Lithium battery capacity loss cause analysis

    Jun , 21 2023
    Lithium-ion batteries are the fastest-developing secondary batteries after cadmium-nickel and nickel-hydrogen batteries. Its high-energy properties make its future look bright. However, lithium-ion batteries are not perfect, and their biggest problem is the stability of their charge-discharge cycle. This paper summarizes and analyzes the possible causes of capacity attenuation of Li-ion batteries,...

    Household storage market and profit model

    Aug , 04 2023
    1.1 The general trend of new energy has been set, and the energy storage industry is rising New energy generation is unstable, and the demand for energy storage arises. The power system needs to maintain a dynamic balance, and when the power generation is too high, the electric energy needs to be converted into chemical energy or potential energy and other forms of energy to be stored. In the trad...

  • Why only online UPS topology provides mission critical load protection

    Why only online UPS topology provides mission critical load protection

    Sep , 09 2023
    Why does only online UPS topology provides mission critical load protection? Modern, static UPS systems are broadly classified into three design architectures: on-line, off-line and line interactive. This post describes and compares the three types and explains why – for truly critical loads – online ups topology is the only acceptable approach. Facility executives today face increased demands for...
