  • High Frequency / High Ripple Resonant Chargers: Good or Bad? (part-1)

    High Frequency / High Ripple Resonant Chargers: Good or Bad? (part-1)

    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 ...

    What types of monitoring and recording devices are suited for high rate charging?

    Jun , 20 2022
    The higher the charging rate, the more critical it is to monitor the charging process to prevent permanent capacity loss. In efforts to preserve battery life, Fast and Opportunity charging incorporates a method of monitoring battery electrolyte temperature and/or internal resistance and adjusting charging current as necessary. Although these monitoring devices can have a very positive impact on ba...

    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 ...

    Do Ferro resonant chargers still have a place in battery charging?

    Aug , 15 2022
    One of the larger battery/charger companies selling chargers in the USA have announced that they are no longer manufacturing Ferro resonant chargers and have set 7/31/15 as the last date to accept orders.Is there something wrong with Ferro resonant charging that should make all charger companies follow that lead? Let’s consider Ferro resonant technology. The purpose of a Ferro resonant transformer...

    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...
