摘要
Abstract
Based on the two-stage(AC/DC and DC/DC)structure of a DC charging pile for electric vehicles(EVs)and through the analysis of the functional requirements of the two-stage circuit structure,a MATLAB/Simulink simulation model is built with a main circuit which consists of a Vienna circuit as the front-stage AC/DC rectifier and a Buck-Boost circuit as the rear-stage DC/DC voltage conversion circuit.Simulations are performed with load set as a pure resistive load and the PNGV model of a battery,respectively.Simulation results meet the requirement of parameters such as output voltage stability accuracy,output voltage ripple and input current harmonics,which proves that the model can be used to analyze the power grid loaded by EVs and promote the study on the impact of EVs on power grid.关键词
