Abstract: A new parallel-connected power flow technique is proposed to improve the input power factor with simultaneously output voltage regulation taking consideration of current harmonic standards. Paralleling of converter modules is used in medium-power applications to achieve the desired output power by using smaller size of high frequency transformers. A parallelconnected interleaved structure offers smaller passive components with less loss in continuous conduction inductor current mode and also reduces the volt-ampere rating of resonant (DC/DC) converter. MATLAB/SIMULINK is used for implementation and simulation results show the performance improvement.
