Abstract:
This paper presents a practical (experimental) and theoretical (through simulation) approach of a prototype of full-bridge DC-DC power converter driven under a hard-switching control algorithm modeled in the MATLAB / Simulink software environment and compiled on a dSPACE control hardware. The experimental approach involves the use of new-generation power modules with semiconductor components made of silicon carbide (SiC). Starting from the preliminary gathered experimental data and from the acquired waveforms, which expose the operating behavior of the proposed converter design at different switching frequencies and loads, an equivalent model of the experimental assembly was built in the MATLAB / Simulink software environment. Based on parallel investigations (practical and theoretical), this paper responds whether the preliminary performance of the converter is satisfactory, so that it can be further used as a charging module in (fixed or mobile) charging systems and supply systems for (partially or fully) electric vehicles. Also, it is analyzed what further improvements may be adopted so that a future designed charging module may be suitable for the conversion of energy supplied from both, conventional and unconventional energy sources.
As the industry places more and more emphasis on the development of both, partially and fully electric vehicles, improving and analyzing the concepts of electric power systems is a priority.
