Using laboratory development system LaunchPad with TMS320F28069 processor and additional BoosterPack module, buck converter is realized. Existing application, as well as the principle of the operation are described in detail, and with using the add-on applications such as Compensator Designer and Software Frequency Response Analyzer, the results are obtained by different methods of regulation. In addition to existing applications that allow changing the controller parameters and calculation of the Bode diagram, a programmed code is added to enable the results of system step response. System step response as well as the transient load response were measured using an oscilloscope, since the ADC of LanuchPad development system fails to meet the measurement dynamic requirements (low frequency sampling of ADC). Furthermore, the results of the implemented system are compared with the results obtained using analytical methods and simulation. The results are very similar when comparing Bode diagrams and step responses, but due to differences appearing in a simulated model (adding an additional delay in the discrete transfer function block), one can see the difference in transient response that is not drastic, but it is certainly noticeable. Because of the differences in the models, in the implementation process should be approached with caution, to avoid unpredictable errors. Furthermore, with acquired basic knowledge of digital control it is possible to implement advanced digital controller that uses auto-tuned parameters, in order to improve the characteristics of the system.
