| Summary: | This paper deals with the structure of the buck converter circuit and the influence of the inappropriate values of its electrical components on the trend of its output voltage. In this perspective, a further study is established on the variation of the inductance, the capacity and the load. As a result, an observation of their impacts on the behavior of the converter is performed. Therefore, when the inductance value is low and the capacitance value is defined as large, the system tends to be more stable and faster. The optimal values of these two components have been considered within the converter circuit in order to closely observe the output response. Indeed, the obtained response has been the most stable and the faster. In this context, a comparison has been made between the calculated values and those obtained during the simulation on Matlab/Simulink. A small difference is observed between the both. On the other hand, the variation of the load resistance only influences the stability of the system, seen clearly for important values.
