| Abstract | In this paper, a novel circuit topology of the active auxiliary edge resonant snubber suitable for high power soft switching inverter applications which has some salient features as compared with conventional auxiliary resonant pole type snubber is proposed in order to minimize the switching power losses of power semiconductor devices (IGBTs) in addition to the switching surge related electromagnetic noises (EMI/RFI) in high power conversion conditioning and processing circuits on the basis of the voltage source type sinewave PWM inverter and voltage source sinewave PWM PFC converter as well as bi- directional PWM converter used as the battery energy storage system. This resonant snubber-assisted inverter topology suitable for high power conversion is described and discussed on the basis of soft switching transition and commutation operation of the voltage source type high efficient pulse modulated inverter. The operation principle and operating characteristics of this active auxiliary snubber circuit are respectively described, together with the practical design procedure of this unique edge resonant snubber. Furthermore, the three phase soft switching sinewave PWM inverter with the novel auxiliary active edge resonant bridge leg link snubbers treated here is evaluated and discussed as compared with three phase hard switching sinewave 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.
