In this paper, a 10 kW current-fed DC-DC converter using resonant push-pull topology is demonstrated and analyzed. The grounds for component dimensioning are given and the advantages and disadvantages of the resonant push-pull topology are discussed. The converter characteristics and efficiencies are demonstrated by calculations and prototype measurements.
The effects of switching asymmetry and flux walking on an isolated current-fed full-bridge boost converter are presented with two different secondary configurations: a voltage doubler (VD) and a diode bridge (DB). The results show that a drop in the converter efficiency is clearly visible when there are switching asymmetries in the DB configuration, whereas the VD configuration is more tolerant of...
