Description
Summary:In this contribution a comparative study of the steady-state and dynamical characteristics of series-parallel resonant converter by using different modulation strategies is presented. Comparison results show that a considerable reduction of switching frequency range, resonant current stress and semiconductor losses as well as a dynamical improvement can be achieved by optimizing the modulation strategy.
