| Abstract | Growing numbers of consumers distort AC networks with harmonics. Therefore suppression of the network pollution should be considered. This problem can be solved by using "network-friendly" converters. In this article some consumers are presented that pollute the single-phase AC networks with harmonics. Therefore the network voltage waveform will be distorted. In our study we examine the features of sinusoidal and resistive current loads that connect to the distorted single phase AC network. If adequate current control strategies are used for network-friendly converters then these behave like sinusoidal or resistive current loads of the network. In this article we are dealing with two current control strategies of single phase four quadrant converters (4QS). The examined sinusoidal and the resistive current control strategies are known, but the differences between the two methods have not been studied before. This paper deals with the comparison of these two strategies. First, the analytical examination is presented. By comparing their consumed RMS currents we defined a coefficient (k[%]), which depends only on the total harmonic distortion of the network voltage (THD). We demonstrated that at high THD resistive current control method is more favorable. Then simulation examination is discussed, by presenting our model of the 4QS. Finally simulation results are represented and compared with the analytical results. |

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.
