| Abstract |
In this paper, the authors deal with the behaviour of the frequency controlled DC/DC series resonant converter. As far as the efficiency and the power to weight ratio are concerned such a converter bears attractive features; however, its control problem are a well-known drawback. The modelling method developed allows expressing a transfer function that links the output voltage to the switching frequency for any operating conditions. The model obtained shows that the dynamic characteristics depend on the operating point to a large extend. The results are shown in the output plane and the dominant behaviour zones corresponding to the connected load are displayed. The theoretical results are compared with simulation and experiment results. |
