Abstract: In hybrid power sources or in electric vehicles, the promising concepts for these are multiport converters. They are much beneficial as conversion can be done in single stage while even interfaced with multiple input power sources. This paper presented the introduction and comparison of multiport converters with conventional converter. Here I present the application of multiport converters with reference to use of multi sources along with the advantages and disadvantages of both, the types of converters. Due to the flexibility of a multiport converter, it gives several advantages. It can be used for many applications as electric vehicle, renewable energy sources for Uninterruptible Power Supply without storage, or it can be used for storage of energy using hybrid sources.
