PV-Grid based Electric Vehicle Charging Station with Modified Interleaved Boost Converter

ABSTRACT

Due to numerous shortcomings of the existing automobiles, the future of transportation lies in Electric Vehicles (EVs). For the sustainable existence of EVs, the development of charging infrastructure based on renewable sources is necessary. Hence, this research article aims to develop a PV–grid topology-based EV charger. An experimental prototype of the EV charging station (EVCS) is developed having a modified interleaved boost converter (MIBC). The proposed charger setup is tested by charging a PV on an EV with a Li-ion battery. The MIBC proposed is analysed and compared with the conventional boost converter, which is also based on PV-grid topology. The testing verifies that the current ripples, conduction and switching losses are reduced significantly. The results conclude that the prototype charger developed is robust, efficient and reliable.
