  1. 1. Design, simulation and evaluation of two different topologies for the 2.4 MW 4/6 kV DC-DC fullbridge converter

    H-uppsats, Chalmers tekniska högskola/Institutionen för energi och miljö

    Författare :Majid Fazlali; Maziar Mobarrez; [2012]
    Nyckelord :DC-DC fullbridge converter; hard-switched converter; soft-switch converter; zero-voltage; switching; phase shift control; switching losses; high power density transformer;

    Sammanfattning : In this thesis, a hard switched and zero-voltage switching fullbridge converter for high power applicationsare compared in terms of their losses. Important issues in designing these kind of converters are to achievehigh efficiency with low cost and low weight. LÄS MER

  2. 2. Evaluation of a non-isolated charger. Concept, analysis and reference design.

    H-uppsats, Chalmers tekniska högskola/Institutionen för energi och miljö

    Författare :Robert Nyström; Yuxuan He; [2012]
    Nyckelord :non-isolated; Power factor correction; onboard charger; bridgeless; fullbridge;

    Sammanfattning : This report discusses the necessity of a galvanic isolation in an onboard charger for aPlug-in Hybrid Electric Vehicle. It was hypothesized that the galvanic isolation was asource of losses, and it is known that the use of galvanic isolation give rise to highercosts and it requires more space. LÄS MER

  3. 3. Design of a 2.5kW DC/DC fullbridge converter

    H-uppsats, Chalmers tekniska högskola/Institutionen för energi och miljö

    Författare :Christian Andersson; [2011]
    Nyckelord :;

    Sammanfattning : In this thesis, an isolated 2.5kW fullbridge DC/DC converter has been designed and analyzedregarding its efficiency and weight.By increasing the switching frequency, the magnetic components in the converter can be madesmaller, in this thesis a switching frequency of 20 kHz has been compared with a switchingfrequency of 100 kHz.
