Analysis of the double quadratic buck converter

The analysis DC-DC Double Quadratic Buck Converter is presented in this paper. This converter has the advantages of high static gain compared to the conventional Buck Converter. The topological symmetry reduce the stress voltage over the switches to half of the value compared with the conventional Quadratic Buck Converter and simplifies the modeling of the converter. The analysis is made for continuous, critical and discontinuous conduction mode and boundary curve between the conduction modes is shown. Finally, the simulation and experimental results are presented to prove the theoretical analysis.
