    What is the meaning of float charging for intelligent three‐stage charger in battery charger?

    Jul , 12 2024
    Float charging: Keep constant voltage charging, the charging current continues to decrease, and the battery is charged with maintenance type. When the charging current decreases to the set value or the charging time reaches the set value, the red light of sufficiency will be on, and the time will be about 2H, charging 10% of the power. Ordinary chargers are old‐fashioned chargers, charging, whethe...

    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...

    Methods for reducing ripple voltage

    Jun , 06 2024
    Brief introduction Ripple voltage is a voltage fluctuation in the output of a DC power supply, referring to the AC component of the output voltage. Excessive ripple voltage can have an impact on the normal operation of electronic devices, so reducing ripple voltage is an important issue that needs to be addressed in the power supply design process. This article will introduce some commonly used me...

    Measures to suppress harmonics

    May , 11 2024
    The fundamental cause of harmonic generation is due to nonlinear loads. When the current flows through the load and does not have a linear relationship with the applied voltage, it forms a non sinusoidal current, resulting in harmonics. The suppression of harmonics in the power system is to reduce or eliminate the harmonic current injected into the system, in order to control the harmonic voltage ...
