Ripple DC/DC Converter Built According to the SEPIC Topology
Abstract
Mathematical models are the base for unified methods of calculating and designing radio-electronic devices. The developed limiting continuous mathematical model of a DC/DC converter built using the SEPIC topology allows us to estimate the range of changes in currents flowing through the windings of the inductors and voltages on the capacitor plates, as well as determine their maximum and minimum values for various converter parameters, such as the power switching frequency key, fill factor, element values, etc. The research results show that the phase coordinates of the mathematical model tend to the real values of the currents and voltages of the converter when the switching frequency of the power switch is more than 200 kHz. A correspondence was established between the calculated values of the ripple ranges and the results obtained during modeling (with changes in the duty cycle and switching frequency of the power switch).
