Abstract

This work presents the operation and design of an AC-DC boost interleaved power factor correcting preregulator circuit using a nondissipative snubber and operating at 100 kHz per cell. By using interleaved converters, one can obtain an overall reduction of the boost inductor, together with reduced switching losses. The complete operating principles, theoretical analysis, relevant equations and simulation results are presented. Experimental results of a prototype rated at 500 Watts, with an input AC voltage of 150 Vrms and, an output of 250 Vdc has been obtained in laboratory
