  • Lead-acid battery failure model

    Lead-acid battery failure model

    May , 11 2024
    The most common failure modes are:   - Softening or shedding of the active material.  During discharge the lead oxide (PbO2) of the positive plate is transformed into lead sulfate (PbSO4), and back to lead oxide during charging. Frequent cycling will reduce cohesion of the positive plate material due to the higher volume of lead sulfate compared to lead oxide.    Corrosion...

    A brief introduction to EMI

    Jun , 14 2024
    What is an active power filter Active Power Filter (APF) is a new type of power electronic device used to dynamically suppress harmonics and compensate reactive power, which can compensate for harmonics and reactive power changes in magnitude and frequency. The reason why the active filter is called active, as the name suggests, the device needs to provide a power supply (to compensate for the har...

    Transient Recovery Time: The time it takes for the output voltage to return to the specified range when there is a sudden change in load (0‐100%, 100%‐0), usually on the order of seconds (ms). Filter: a device used to eliminate noise, the input or output filtered to obtain a pure contention of the alternating current. Shielding: The use of physical principles, used to isolate the electromagnetic r...
