Abstract

A full bridge high-frequency link series parallel resonant converter (SPRC) operating in discontinuous current mode is analyzed using the state-space approach. The equations are solved using the PROMATLAB software. Design curves for the converter gain and other component stresses are presented in normalized form. The converter has been optimized for peak component stresses, and the corresponding design curves obtained from PROMATLAB and SPICE3 simulation are presented. Using the optimal design curves, a 250-kHz experimental converter operating on a wide input voltage (1:2) has been built to verify the theoretical and SPICE3 simulation results
