**5. Conclusion**

This chapter gave a general overview of AC and DC converters with special emphases on DC-DC converters and their applications. The different topologies were discussed and the importance of designing for efficiency and energy saving was emphasized. Design and analysis steps were illustrated using Matlab and Simulink as an engineering tool. The effectiveness of the SimPower toolbox was demonstrated via typical examples which lead the way for further investigation. The tools available for simulation were exploited to facilitate additional related studies.
