The DC sources like fuel cells, solar cells, storage units need to raise its output voltage in order to match load requirements. So often these systems are equipped with Power Electronics techniques in general and DC-DC booster converters in particular. The paper provides the mathematical model and algorithm for designing the booster converter with selected values in order to define the values of the most important parameters of its components including inductor parameters. Based on the developed algorithm, a simulation of the system is conducted in MATLAB / Simulink environment to analyze the impact of changing the inductor inductance on booster performance. Also the paper includes the mathematical model and algorithm for designing the booster inductor in terms of material, conductor type and shape of core and number of windings. Based on the design results, the inductor has been implemented completely in the laboratory. The inductance of the implemented inductor has been measured using a number of measuring methods to make sure of its value and match it with the theoretical values of design. Finally, the developed algorithm has been translated into a program in an environment Matlab / GUI , with which several computer tests have been performed.
