| Abstract | In this paper, a new full soft switching high step-up DC–DC boost converter is proposed. To achieve high voltage gain, a N-level voltage multiplier cell (VMC), and to achieve soft switching, a simple auxiliary resonant cell is implemented on a conventional pulse width modulation boost converter. All semiconductor devices are switched under soft switching conditions, which decrease the switching losses significantly. These soft switching conditions consist of zero voltage and zero current switching (ZVZCS) condition for both main and auxiliary switches, ZVZCS for auxiliary cell diode and zero current switching for all output VMC diodes. To control the output voltage in this converter, two degrees of freedom, consisting of the main switch duty cycle and output VMC level (N), are available. These degrees of freedom lead the converter to operate in a wide output voltage range and have maximum power point tracking implementation or output voltage regulation capabilities. In this paper, operational modes analysis, design procedure, application discussion, soft switching and power efficiency evaluations and simulation results are presented. Finally, experimental results with input voltage of 32 V, output power of 80 W and switching frequency of 20 kHz are given to prove the accuracy of theoretical analysis. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
