  • Efficiency of DC power system

    Efficiency of DC power system

    Jun , 27 2022
    In this article we will explain the efficiency of DC systems and progress to AC systems on the next article. In very basic terms, efficiency is the measure of how much power is not being wasted by a system. More waste is less efficient. In electrical systems, we measure the power entering a system in watts; the unit of measure for work performed. Efficiency is the ratio of (Power-In) -vs. - (Power...

  • High Frequency / High Ripple Resonant Chargers: Good or Bad? (part-3)

    High Frequency / High Ripple Resonant Chargers: Good or Bad? (part-3)

    Jun , 13 2022
    Battery charging is a complex electrochemical process, in which the discharged electric energy is replenished from the electric power grid. This is accomplished using a battery charger, which is an electrical/electronic device that converts the incoming AC line voltage into a regulated DC voltage to meet the charging needs of the respective battery. In a series of articles we are going to explain ...
