| Abstract | In electric drive applications, the conventional carrier based and space vector pulse width modulation (PWM) which schemes for two-level inverter topology generate large common-mode voltages, this leads to the phenomenon of bearing current. These current spikes can cause electromagnetic interference (EMI) and reduction in the life expectancy of the motor. Cascade multilevel inverters can reduce voltage stress on power switches; generate smaller common-mode voltages and output voltages with low distortion. Phase shifted PWM is a compatible solution for H-bridge cascaded inverters. In this paper, we will present a simple and flexible phase shifted PWM technique for common-mode voltage reduction of a five level H-bridge cascade inverter topology. Simulation results are presented for validation and comparison with other techniques. |

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.
