  • Effect of input capacitors between UPS and Generator

    Effect of input capacitors between UPS and Generator

    Jul , 18 2022
    Input capacitors used for filtering purpose cause pure apparent power to flow between the supply and the UPS. Such power is referred to as leading or capacitive power. Gensets can manage limited amount of pure leading power, as it interferes with the excitation circuit in the AC generator, leading to voltage oscillations and genset’s shutdown. Safe operating area charts show the allowed gensets’ l...

    Solar battery life time

    Aug , 08 2022
    There are two ways to answer this question and the first is to determine how long a solar battery can power your home. In many cases, a fully charged battery can run your home overnight when your solar panels are not producing energy. To make a more exact calculation, you’ll need to know a few variables, including how much energy your household consumes in a given day, what the capacity and power ...

    Power Factor and Harmonic Analysis in PWM converter

    Aug , 15 2022
    Most of the power conversion applications consist of an AC to DC conversion stage and this DC output is then used for further stages. An AC to DC converter is an integral part of most of the electronic equipment as most of these equipment are DC powered [1]. Generally to convert AC to DC a diode bridge rectifier is used. To reduce the ripple in the output voltage a suitable filter capacitor is use...
