| Abstract |
In a resonant DC/DC converter, the major part of the volume is filled by passive
components. Moreover, all these components have to support all the power flow. On the one hand, this
leads to losses in these components and their connections and on the other hand to an important cost of
the converter. This paper will present a new component, called L-C-T, which permits to integrate in an
unique part an inductor, a capacitor and a transformer. Because it uses only one core with 3 windings,
this component will reduce the volume of the passive part of the converter. By reducing the number of
connections it will, also, have a positive effect on losses.
After a presentation of L-C-T components, this paper describes a design of this device, using
new windings disposition. The proposed structure permits to adjust separately L and C values. Then,
to validate the approach, a characterization is carried out, leading to a new model, including dielectric,
iron and copper losses. |
