摘要
随着电动汽车产业的不断发展,电动汽车充电机数量也在不断增加。非车载充电机作为一种电源设备,提高效率可以有效降低其内部热损耗,保证设备的使用寿命。文中通过Matlab/Simulink仿真平台,根据电动汽车非车载充电机的基本原理,建立三相不控整流型非车载充电机仿真模型。通过仿真得到充电机充电过程中的效率曲线,分析了充电机损耗产生原因并提出了相应的解决方法。
With the continuous development of the electric car industry,the number of the electric car charging machines is growing.Improving the efficiency ef off-board charger of electric vehicle can reduce the internal heat loss effectively and guarantee the life of the equipment.This paper establishes a model of the off-board charger by using three-phase uncentrolled rectifier in the Matlab/Simulink environment according to the basic principle.Additionally it presents the charger efficiency curve in the process of charging through simulation,analyzes the energy loss and provides the solution.
