Abstract
Conventional structure of PFC AC-DC converter integrated with DC-DC converter is used in electrical vehicle and battery charging applications. AC-DC converter is to convert AC voltage to specify DC level with near to unity power factor and DC-DC Bidirectional converter is used to charge and discharge the battery at specified operation. These converters preferably used to charge the li-ion battery in lean hours and in peak hour battery is discharged to give power back to grid. A PI controller is used control the battery current and voltages. The operating principle and different mode of operations are clearly discussed in this paper. The Simulink model is developed using MATLAB-Simulink and sim-power system tool boxes and results has been carried out.
