  • Causes of harmonics in rectifier equipment

    Causes of harmonics in rectifier equipment

    Mar , 21 2025
    1. Nonlinear characteristics   The diodes, thyristors and other power electronic devices in rectifier equipment have nonlinear voltammetry characteristics. Take the diode as an example, when the input AC voltage is in positive half circle, the diode is positive and the current can pass through; At the negative half cycle, the diode is reversed off and the current is almost zero. This characte...

  • Difference between kVA and kw

    Difference between kVA and kw

    Mar , 15 2025
    kVA is the unit of apparent power and kw is the unit of active power. In alternating current, apparent power does not indicate the actual power consumed in the circuit, but rather the maximum power that can be supplied or the maximum active power consumed in an alternating current circuit. In the case of active power, it is the power needed to enable the equipment to work properly, such as the ele...
