Abstract:
The paper proposes a novel zero-current-transition(ZCT)push-pull forward converter. The auxiliary resonant cell is in parallel with the main circuit and the zero-current-switching(ZCS)range of the main and the auxiliary switches of the proposed converter are entirely achieved. The resonant capacitor achieves high voltage by operating the auxiliary cell. The auxiliary switch turns on before the main switches turn off, the high voltage of resonant capacitor blanks off the rectifier, and then the current of the secondary windings and the primary windings reaches zero. The operation principle of the new ZCT technique is detailed. And the key parameters to realize ZCS are calculated. The simulation and experiment reveal that the above scheme is feasible. A family of ZCT circuit in isolated converters can be developed by the same principle.
