Design and Control of the WCR-4SSC Boost Converter on a Test Workbench for DC-DC Converters

In this paper, it is modeled the DC-DC Boost WCR-4SSC converter operating within the R2 region (0.33 < D < 0.67) using an equivalent converter approach. This allows the researchers to apply well-established conventional modeling techniques widely recognized in the field of power electronics. To determine the equivalent converter within the specified region, it was defined energy storage intervals within the inductor. Moreover, based on these intervals, it was determined the switching frequency and duty cycle. Finally, it was calculated the input voltage and inductance of the inductor while assuming the output voltage to be equal to that of the converter with a three-phase cell. For the design and validation of this technique, it was considered a three-phase cell converter with the following specifications: V
