In this paper a computer aided design of snubber circuit for DC\DC converter is presented. Due to the presence of parasitic LC circuit in the power stage (inductance and capacitance), it is necessary to use an additional snubber circuit for voltage overshoot and oscillations reduction. A simulation model of the converter with parasitic circuit was designed. Three types of snubber circuits (C, RC, RCD) were investigated in simulation tests. Simulation model of the proposed system has been investigated in Matlab/Simulink/PLECS environment. Input signal parameters like voltage overshoot, rise time, fall time were compared for considered snubber circuits. Experimental tests were carried out for the best simulation result. It confirm the proper choice of snubber circuit.
