The dc-dc converter is crucial for boosting the output voltage of renewable energy sources, particularly wind energy. In this paper, the dc-dc converters: boost converter, flyback converter, push-pull converter, and phase shift full bridge converter (PSFB) will be compared in terms of output voltage, current and power to determine which one is the best. The phase shift full bridge converter was chosen to improve the dc-dc converter's output. Performance of each converter is simulated using MATLAB/SIMULINK.
