Abstract:
The paper will present different methos of converting a conventional flyback topology in a soft switching topology. Several solutions of obtaining ZVS in flyback topology, such as energy injection in magnetizing current, active clamp and current injectionwill be analyzed. A comparison in performances for these methods will be made as well. The paper will address the GaN utilization and its advantages in flyback topology with application in AC-DC adapters with power delivery 3:0. The comparison between GaN and silicon mosfet will be done in the case of standard quasi resonant flyback and also in ZVS flyback. Experimental results will highlight this analysis.
