Analysis on Harmonic Characteristics of Electric Vehicle High-Frequency Charger
Abstract:
As a nonlinear load, a large number of electric vehicle chargers inserted into power might bring many challenges, cause harmonic pollution to power grid. In this paper, a high-frequency charger is regarded as a researching object, the power characteristics of charger, harmonic current and impactive parameters are analyzed, and the harmonic analysis model of the charger accessed to power grid is built. Applying the Simulink and SimPowerSystems toolbox in Matlab and the simulation method facing the systems structure of electrical principle, the model is simulated. The harmonic generative rules and characteristics for a single high-frequency charger are present. The results might forecast the harmonic pollution of charge station, and provide the theory base for choosing harmonic control device and methods.
