Research on Parallel Current Sharing Technique of Electric Vehicle Charging Power Supply

Nowadays charging power supply in electric vehicle current mainly uses parallel with multiple charging power supply method to realize high power output.The principle of multi-mode parallel current sharing which is auto-matically achieved by current control mode charging power supply is studied.It's realized that the inner current loop control outer voltage loop which based on the simulation prototype of LTC3722-1 integrated controller,and the advan-tages and the feasibility of the electric vehicle charging power supply which using the current control mode to realize the multi-mode parallel current sharing are pointed out.
