Abstract :
A series-parallel resonant power converter employing an (LC )(LC)-type tank circuit is presented, and analyzed using complex AC circuit analysis. Design curves are obtained, and the converter is optimized under certain constraints. Detailed SPICE simulation results are presented to evaluate the performance of the designed converter under varying load conditions. Results obtained from an experimental converter are also presented. The results obtained from the theory, SPICE simulation, and the experimental converter are compared. The proposed converter has high efficiency from full load to very light load (<10%). Variation in the switching frequency for a wide variation in the load (load open circuit to full load) is narrow compared to the series resonant converter
