| Abstract | We propose a three-phase buck-boost AC chopper controlled by two phases. Characteristics of the circuit are analyzed by the simulation considering the dissipation of semiconductor devices and inductors. Ripple and total harmonic distortion (THD) of an input current and an output voltage increase when inductive components increase in the load. Variations appear in each phase in buck-boost ratio. The resonance frequency is changed due to the inductive components in the load. The pi-connected output filter is analyzed, and it operates as the second reverse L-connected output filter. THDs in the output voltages are improved when the capacitance in the output filter is changed to adjust the resonance frequency of the output circuit. The three-phase four-wire system is analyzed, and the circuit is compared with the two phases control method. Then, the cause of unbalance at each phase for the three-wire systems is proved to be the two phase control method. |

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.
