Abstract | The recent development in high gain DC–DC converters motivates its application on renewable energy systems with low output voltage such as photovoltaic cells resulting in the requirement of high voltage gain converters with improved static and dynamic characteristics. This study proposes an optimal reduced order linear quadratic regulator controller for a reduced order model of a voltage multiplier cell (VMC) integrated boost converter with two sensors for measuring the output voltage and the input inductor current. The dynamic performance of linear quadratic regulator controller over load, line and component perturbations are shown through extensive simulation studies on the reduced order model developed and the comparison is accomplished with conventional hysteresis current controller in order to disclose the best control technique in terms of dynamic response. The extensive analysis based on simulated results are verified exactly with a measured results in a 100 W prototype operating in continuous conduction mode VMC integrated boost converter controlled using DSPIC30F4011 processor. The control technique proposed computes error coefficients with less computation time, guarantees excellent system stability and offers improved dynamic characteristics for VMC integrated boost converter with reduced number of sensors. |

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.
