| Abstract | Compared with analog control, digital control adopted in PWM inverter possesses the evident advantages but the traditional PID control strategy which is realized in digital method often can't achieve better performance than in analog control. In past references, there is hardly quantitative analysis on the effect of digital process on the performance of PWM inverter. This paper did a creative research about the zero-order-hold process and one-step-delay control effect on the performance of PWM inverter. The process of zero-order-hold and one-step-delay control were analyzed why the digital process influences PWM inverter's performance in this paper. The process of zero-order-hold and one-step-delay control varies the system's stability with sample time. Zero-order-hold reduces the stable scope to a large extent compared with analog control, and limits the performance improvement of digital control system. One-step-delay with different sample time brings different influence on the system stability. Finally relevant experiments in a single phase inverter verify the theoretical analysis on the effect of digital process on the performance of PWM inverter. |

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.
