Modeling and Analysis of a Wide Battery Voltage Range On-Board Electric Vehicle Charger

Abstract

The very known fact that vehicles with IC engines require fossil fuels as their oxygen and in turn emit hazardous gases back to the atmosphere being a paramount benefactor forces us to learn more about eco-friendly vehicles to counter the effect of conventional IC engines: Clearly the Electric Vehicles. In On board charger (OBC), a two-stage converter connect the input grid supply and the battery, whose output levels vary from the vehicle architecture. OBCs are typically offered in voltage ranges: 48-72, and 96-150 V. This work focuses on the study and propose a revolutionary common battery charger for automotive applications with a voltage range of 50-400 V and presents a control mechanism for achieving the inconsistent DC link in the power factor correction (PFC) stage. A DC-DC converter is implemented with the design consideration and control algorithm. In addition, the study simulates and presents a two-stage common battery charger with a broad output voltage range. A high-efficiency common charger that can handle a large range of battery voltages is ideal for charging a wide variety of automobiles.
