  • The working principle of anti reverse diode

    The working principle of anti reverse diode

    Aug , 10 2023
    Anti reverse diode, also known as reverse protection diode, is a component used in a circuit to prevent reverse current from flowing in. This type of diode is usually composed of a PN junction diode. Under normal operating conditions, the pressure difference between its P and N poles will cause the diode to conduct, while under reverse conditions, this pressure difference disappears and the diode ...

  • Selection of the Function of Power Filter Capacitors

    Selection of the Function of Power Filter Capacitors

    Aug , 10 2023
    1 、The Role of Power Filter Capacitors The power filter capacitor is a type of capacitor connected in series between the power output and the load, mainly used to filter high-frequency noise in the power supply and ensure the stability and reliability of the power output. At the output end of the power supply, due to the conversion of AC power to DC power, there will be a certain AC component in t...

  • Characteristics and principle of OPzV colloidal battery

    Characteristics and principle of OPzV colloidal battery

    Aug , 09 2023
    OPzV is made of high-purity nano-scale materials, which can greatly extend the battery life: Principles and features: (1) can effectively inhibit the delamination of lead-acid battery electrolyte, dendrite short circuit and other problems. (2) The adsorption of colloid reduces the supersaturation of PbSO4 and produces loose porous PbSO4: (3) Delay the formation of PbSO4 dense crystalline layer and...

  • Why do lithium-ion battery plates use copper foil for the negative electrode and aluminum foil for the positive electrode

    Why do lithium-ion battery plates use copper foil for the negative electrode and aluminum foil for the positive electrode

    Aug , 09 2023
    For lithium-ion batteries, the usual positive collector is aluminum foil, and the negative collector is copper foil. In order to ensure the stability of the collector fluid inside the battery, the purity of both is required to be above 98%. With the continuous development of lithium technology, whether it is used for lithium batteries of digital products or batteries of electric vehicles, we all h...

  • Household storage market and profit model

    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...

  • Effect of carbon black content on negative electrode performance of lead-acid battery

    Effect of carbon black content on negative electrode performance of lead-acid battery

    Aug , 04 2023
    VRLA battery is not ideal in electric vehicles because of its short life under deep charge and discharge cycle conditions. In recent years, with the improvement of positive plate grid materials, the cycle life of batteries has been improved, and the main reason for the failure of VRLA batteries for electric vehicles is the sulfation of the negative electrode. To this end, there are more studies on...

  • Industrial UPS with Ride-through Protection

    Industrial UPS with Ride-through Protection

    Jul , 28 2023
    Introduction Electrical utilities use reclosers on medium voltage supply to isolate faults caused by events such as lightning strikes, tree branches across lines, or animals making contact with live wires. The result of a recloser operation is a momentary power outage, lasting for up to a few seconds. These outages can cause an unplanned production stoppage which can be very costly. When momentary...

    Explanation of power terms related to UPS power supply

    Jul , 28 2023
    Transient recovery time: The time required for the output voltage to recover to the specified range when the load suddenly changes (0-100%, 100% -0%), usually in milliseconds (ms). Filter: A device used to eliminate noise, filtering the input or output to obtain pure alternating current. Shielding: A means of isolating and blocking electromagnetic radiation using physical principles...
