Comparative analysis of various restructured Quadratic Boost DC-DC converter

Abstract

In this article, five high gain topologies are derived by reconfiguring the conventional quadratic boost converter. This restructuring is carried out by integrating high gain cells and modifying the topology. The voltage conversion ratio of the topologies is derived using steady-state analysis. Each topology is compared with alike converters in the literature with respect to voltage gain, stresses across the devices and total component count. With this comparative study, the superiority of the suggested topologies is highlighted. Finally, the simulation results of the five topologies are obtained from PSIM software and the results are presented to validate the theoretical results.
