Practical Buck DC/DC Converter Theoretical and Experimental Evaluation

In this paper is presented the study of a buck DC/DC converter via mathematical modelling and then a comparison is made against experimental studies via electronic EVM board. The main goal is to evaluate the feasibility of the model for studies, related to the verification of the design and operating regimes of buck DC/DC converters. The EVM allows for change of the circuit elements, hence the parameters of the DC/DC converter and by studying their influence, it can be concluded how that affects the steady-state operating regimes. By using model-based evaluation one can view the study as a useful tool in design stage for taking decisions about the building blocks and components, which will be used in the design. The study can also be very useful for students and trainees to verify the influence of the passive filters in the converters.
