Design of Boost Integrated Luo Converter for Grid Tied EV Based Charging Station

Abstract

The combination of Renewable Energy Source (RES) and storage element in charging station is a possible solution for meeting the growing energy requirement of electric vehicles (EVs). In a grid-tied RE system, the converters are essential for attaining the process of power conditioning. Conventional DC-DC converters suffer from issues like voltage spikes, electromagnetic interference, and efficiency losses. The necessity for integrated converters arises from the demand for improved power conditioning, increased power density, and enhanced overall system performance. As a result, in this work, boost integrated Luo converter is proposed due to the ability to address aforesaid drawbacks and offer superior power conditioning capabilities in modern power electronic systems. The Luo converter with conventional boost converter aids in alleviating the current ripples to a greater extent. The PI control with Particle Swarm Optimization (PSO) strategy is efficiently employed in this study as provides consistent voltage supply to the converter. Thus, the ultimate aim of this work is achieved by enhancing the low dc voltage of PV panel by using a PSO-PI control-based hybrid converter, which increases its efficiency, lowers the cost, supplies suitable current and voltage for energizing the battery or to charge the grid tied EV charging station. The simulation results obtained verifies the effectiveness of developed system.
