Abstract

This paper will present the optimization design for medium size converter with high switching frequency for household appliances. The series resonant LLC half-bridge converter, 1 kW, 48V and 600 kHz with coreless transformer has been chosen for the power transferring. System verification has been done by MATLAB/Simulink program, which used to find the optimized parameters and converter output under designed conditions.
