  7. 5. Designing and Maximizing Switch-Mode Efficiency of MODPSU, the Modular Power Supply

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Niclas Arndt; [2016]
    Nyckelord :DC DC; SMPS; optimization; power supply; Technology and Engineering;

    Sammanfattning : This work is an investigation into practical design and loss minimization of DC/DC-switched power supplies, enabling cooler operation, smaller size, and additional or wider areas of use. There is an abundance of switch controller ICs on the market and a few of the manufacturers offer very sophisticated design tools that suggest operating parameters and grade components. LÄS MER
