<b>Power Electronic Interface</b> Distributed energy units cannot be directly integrated into the power grid due to their inherently varying output. An interfacing technology is required. The power electronic interface is used for connecting distributed energy resources to the smart grid. It can also be used in any type of electric vehicles. It does not store energy in its circuitry. It receives power from the distributed energy source and converts it to power at the required voltage and frequency. This paper provides a brief introduction on power electronic interface. power electronic interface, multiport power electronic interface 21-23 Issue-1 Volume-4 Matthew N. O. Sadiku | Adedamola A.
