  • How is ups efficiency calculated?

    How is ups efficiency calculated?

    Dec , 09 2023
    UPS efficiency is a big deal. The more efficient your UPS, the cheaper it is to run. As energy costs continue to increase, we’ve seen that businesses and organisations across multiple sectors are now looking for ways to increase their energy efficiency and subsequently reduce their energy bills. One of the ways to do this is by investing in an efficient uninterruptible power supply (UPS). What is ...

  • What is the difference between UPS linear load and non linear load?

    What is the difference between UPS linear load and non linear load?

    Nov , 29 2023
    AC electrical loads are referred to either as linear or non linear load depending on how they draw current from the mains power supply waveform. Linear Load UPS loads where the voltage and current waveforms are sinusoidal. The current at any time is proportional to voltage. Linear load is: POWER FACTOR IMPROVEMENT CAPACITORS, INDESCENT LAMPS, HEATERS ETC Non Linear Load Applies to those UPS loads ...

  • What is the ups power factor?

    What is the ups power factor?

    Nov , 17 2023
    Power factor (pf) is the difference between actual energy consumed and the apparent powerin an AC circuit. It will calculate as a decimal or percentage between 0-1 pf and 0-100% i.e. 0.9 pF = 90%. UPS input power factor The UPS input power factor is the ratio of UPS input active power to input power. UPS is not only a part of power supply, but also a load on the utility power source. It means the ...

  • What is single phase ups?

    What is single phase ups?

    Nov , 17 2023
    Single phase UPS has a single input and output source to the electrical equipment. With just one sinewave voltage, it only requires two wires to complete the circuit, one conductor and one neutral. Single phase UPS uninterruptible power supplies typically cover requirements up to 30 kVA. They are for servers, telecoms or computer systems, and network switches. Also they are along with any device t...

  • The working principle and control method of IGBT voltage modification method

    The working principle and control method of IGBT voltage modification method

    Nov , 03 2023
    Unlike the resistance method, the voltage method involves changing the driving voltage during the control phase to control voltage and current overshoot. There are approximately two methods to change the driving voltage. One is to achieve the change by dividing the driving voltage through a resistor, and the other is to change the output signal in the control chip (DSPFPGA), and then convert it in...
