@article{Stepins_2010, title={Examination of Power Converters with Modulated Switching Frequency}, volume={105}, url={https://eejournal.ktu.lt/index.php/elt/article/view/9164}, abstractNote={In this paper analysis of output voltage ripples of a switching frequency modulated (SFM) boost converter operating in continuous conduction mode is performed. The ripples are analyzed in both time and frequency domains theoretically and using computer simulations. Increase in output voltage ripples is observed after using periodic SFM. Low frequency output voltage variation is revealed to be the most problematic. Cause of the problem is found out. Influence of main non-idealities of the boost converter and modulation parameters on the output voltage ripples is also analyzed. Experimental verification is also performed to confirm the theoretical evaluation and simulation results. Some recommendations are given to improve usefulness of periodic SFM in boost converters.}, number={9}, journal={Elektronika ir Elektrotechnika}, author={Stepins, D.}, year={2010}, month={Oct.}, pages={33-38} }
