Abstract: Power Electronics (PE) deals with the conversion and control of electric power in different energy systems. The PE topologies are found as a better option as compared to the mechanical techniques used earlier for Renewable Energy Systems (RES) due to the flexibility, sensitivity, bi-directional power flow control, fast switching capabilities and other important characteristics. This paper mainly reviews the current PE topological approaches used for the generation, transmission and distribution part. Generators used between generation and transmission part are mainly classified into Synchronous, Induction and Doubly-fed Induction Generators (DFIG). For the sustained and continuous output from these generators various control techniques (Scalar, Vector, and Matrix Controller) are used. For the distribution part grid integration techniques which include grid synchronization, control and microgrid are discussed in the paper. Further, the paper reviews the most recently proposed advancements for the development of these techniques. As a result, the study finds the issues and challenges in the modern PE systems and a future pathway is conceptualized
