Self-oscillating half bridge series resonant converter at high efficiency

In this paper we will going to study and test the command of an self - oscillating half bridge resonant converter operating in commutation soft ZVS. To simplify the command and the reduction of the cost, we opted for a self - oscillating structure based on the use of the saturable core in ferrite. They assure automatically the turn-on and the turn-off of transistors without any exterior control. And this in a totality of the operating, in light load, in on-load and in short circuit load. A prototype is implemented and the operation principle is verified by the experimental results.
