Submitted: Jun 8, 2013; Accepted: Jul 17, 2013; Published: Jul 25, 2013 Abstract: In this paper different types of converters based on different types of switching cells have been studied and designed. The analysis of each converter has been carried out. The main objective of analysis is to find out the advantages and disadvantages of each converter and to find the converter suitable for the given application. The analysis of these converter result in a new converter. The proposed converter posses high voltage conversion ratio and reduced switch voltage stress. The principles of operation and the theoretical analysis of each converter have bee presented in this paper. The different converters have been simulated and their results are compared. In order to verify the theoretical results the proposed converter is simulated for 35 W prototype operating at 100 KHz.
