Abstract :
The proposed method offers an improved DC/DC converter scheme to increase power density. It is based on half-bridge topology with a newly introduced pulse-grouping control method, which helps to reduce the transformer size and the volume of semiconductor devices, maintaining high efficiency. Test results with 85 W (18.5 V/4.6 A) design shows that the measured efficiency is 93.5% with power density of 36 W/in3.
