| Abstract: | In view of the new requirement of DC charger put forward by State Grid in recent years,a DC charge with constant power is designed. On the basis of MATLAB simulation analysis,the software and hardware of the system are designed,including three-phase uncontrolled rectifier circuit,DC-DC hardware module,auxiliary power supply and DC-DC controller. The system realizes the AC-DC conversion,DC-DC buck conversion,and the constant power charge of the battery. The experimental results show that the system can use the capacity of the charger to the maximum extent,and the effect is better than that of the constant current and voltage charger. |
