    The working principle of thyristor

    Aug , 07 2024
    As is well known, resistors are ubiquitous in daily life. We can use resistors to turn on and off small currents, and convert small currents into larger ones. But when dealing with larger currents, they are not very effective, and there is also a disadvantage that once the switch current is removed, they cannot work, which means they are not as useful in devices such as alarms. Thyristor, also kno...

    The way the thyristor rectifies

    Aug , 07 2024
    A Thyristor rectifier is a power electronic device that is widely used in the conversion process from alternating current to direct current. It achieves a unidirectional flow of current by controlling the turn-on and cut-off of the thyristor, which converts alternating current into direct current. Thyristor rectifiers are characterized by high efficiency, reliability and fast response. How thyrist...

  • How to extend the power supply time of uninterruptible power supply (UPS)

    How to extend the power supply time of uninterruptible power supply (UPS)

    Aug , 03 2024
    There are two ways to extend the duration of an uninterruptible power supply: 1. Increase battery capacity. According to the length of time required to increase the number of batteries, but this method will cause a relative increase in battery charging time, but also increase the number of corresponding maintenance equipment, increase product size, resulting in an increase in the overall cost of U...

    Working principle of inverter

    Jul , 26 2024
    Input interface section: There are three signals in the input section: 12V DC input VIN, working enable voltage ENB, and panel current control signal DIM. VIN is provided by the Adapter, and ENB voltage is provided by the MCU on the motherboard, with a value of 0 or 3V. When ENB=0, the inverter does not work, while when ENB=3V, the inverter is in normal working condition; The DIM voltage is provid...

    What is hot-dip galvanizing and galvanized aluminum-magnesium

    Jul , 20 2024
    What is hot-dip galvanizing of photovoltaic brackets? The hot-dip galvanizing process is also called hot-dip galvanizing. It is to immerse the steel bracket after cleaning and activation in molten zinc liquid. Through the reaction and diffusion between iron and zinc, a zinc alloy coating with good adhesion is plated on the surface of the steel bracket to form a hot-dip galvanized bracket. It is a ...
