Design and analysis of hybrid DC-DC boost converter in continuous conduction mode

Abstract

This paper presents the design and analysis of Hybrid DC-DC Step-up converter in continuous conduction mode (CCM). The proposed Hybrid DC-DC boost converter consists of conventional boost converter which incorporates switched capacitor cell-UP1. It provides high DC-DC voltage conversion(60 V-380 V) and eradicates the complexity in conventional boost converter while operating in high duty ratio. A small structure changes has to be made to convert conventional boost converter into a hybrid switched-cell-based boost converter. There are six different types of switch cells, of all UP1 cell has been used in this converter. The output results are validated with the help of simulation using MATLAB/SIMULINK. The performance, such as dc gain, voltage and current stresses on the actives witch, currents through the inductors are shown in output wave forms.
