Multiport Fast Charger on the Concept of Active Power Electronic Transformer

This paper describes a novel three-port hybrid fast charger for plug in electric vehicle, electric bike and transferringmomentary power from ultra-capacitor to charging station when there is no supply from grid as well as PV array.Here the three-port active power electronic transformer is considered. The topology consists of a hybrid chargingsystem which consists of utility grid, batteries, PV panels and ultra-capacitors which are connected via a three-portpower electronic transformer. Various energy storage systems are connected to each other via full bridge inverters.This system helps to control voltage, current and power rating thereby adequately charging the electric vehicle/bike.The proposed topology has been verified using MATLAB simulations and hardware has been constructed. The paperpaves the way of effective coordination and efficient use of utility grid, battery and super capacitors in EV charger.
