| Abstract | This paper presents a digital repetitive control scheme for the minimization of output voltage total harmonic distortion (THD) of a PWM inverter under large unknown nonlinear load. The multi-phase interleaved PWM inverter has been adopted to enhance the effective switching frequency as well as to share the load current. The realization of a digital control for PWM inverter, such as sampling delay and quantization error, may introduce many nonlinear effects to distort its output waveforms. A systematic design procedure is developed to minimize selected range of harmonic spectrum by shaping the output impedance by so that its output voltage THD can be lower than a specified value with given design constraints. The proposed control scheme has been realized with fully digital design by using a single-chip FPGA implementation and verified by using co-simulation technique via a VHDL simulator Modelsim combined with a system-level block diagram oriented simulator Simulink. |

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.
