Abstract: Switched mode DC-DC converters are some of the simplest power electronic circuits which convert one level of electrical voltage into another level by switching action. These converters have received an increasing deal of interest in many areas. This is due to their wide applications like power supplies for personal computers, office equipment, appliance control, telecommunication equipment, DC motor drives, automotive, aircraft, etc. The analysis, design, control and stabilisation of switching converters are the main factors that need to be considered (Verma et al., 2013). In brief, DC/DC converters are used to generate multiple DC levels for powering the circuits in a device, they are also used to reduce ripples, i.e., they carry out two main functions: modify the voltage level (step-up or step-down), regulate voltage. This paper first reviews the commonly used DC-DC converters in portable power device, namely, buck and boost converters, and then a model for a buck converter using MATLAB/Simulink is illustrated and simulated in both open loop mode and using a PID controller.

Keywords: DC/DC converters; mobile applications; MATLAB/Simulink; buck and boost converters; PID controller.
