Designing Synchronous Buck converter always evolve around two major criterions: quality of output load and power dissipation of the converter. While quality of the converter can be relatively easier to be achieved by controlling the values for all the elements carefully using even conventional schemes, techniques to handle and optimize power dissipation is often sophisticated and complex. In this paper, the techniques used for implementing lower power dissipation such as Resonant Gate Drive and PWM scheme are investigate. Then the simulations are carried out to verify the theories. © 2012 IEEE.
