Abstract :

The Rapid Expansion Of Electric Vehicles (EVs) Necessitates The Development Of Efficient, Compact, And Reliable On-board Charging Systems. This Paper Proposes A High-efficiency EV On-board Fast Charger Based On A Three-port Partial Power Processing (PPP) Converter Integrated With A Sliding Mode Controller (SMC). The Proposed Topology Facilitates Simultaneous Bidirectional Power Flow Among The Grid, Battery, And Auxiliary Energy Storage, Enabling Flexible And Intelligent Energy Management. Unlike Conventional Full Power Processing Converters, The PPP Approach Significantly Reduces Processed Power, Thereby Minimizing Switching Losses, Thermal Stress, And Component Ratings While Improving Overall Efficiency And Power Density. The Incorporation Of SMC Ensures Robust Performance Under Parameter Variations And External Disturbances, Offering Fast Transient Response And Precise Voltage Regulation. The System Operates In Multiple Modes Depending On Grid And Battery Conditions, Ensuring Optimal Power Distribution During Charging And Auxiliary Support Operations. Simulation Studies Validate The Effectiveness Of The Proposed Method, Demonstrating Superior Dynamic Response, Reduced Output Voltage Ripple, And Improved Efficiency Compared To Traditional PI-controlled Systems. The Proposed Charger Achieves A Peak Efficiency Exceeding 96%, Making It A Promising Solution For Next-generation EV Charging Applications
