Abstract :
The forward zero voltage switched (ZVS) multiresonant power converter (MRC) and the class-E derived single ended parallel (SEP) MRC are compared on the basis of their relative current and voltage stresses, and efficiency for 50 W on-board power applications. The comparison is performed using SABER large-signal simulations with experimental verification of the results. It is found that the forward ZVS-MRC operates with lower current and voltage stresses under full load conditions, whereas the SEP-MRC operates with lower current and voltage stresses under light load conditions. As a result, the full-load efficiency of the forward ZVS-MRC is higher than that of the SEP-MRC, but the efficiency of the SEP-MRC is less dependent on load variations
