Applied Research of Improved Passive Power Filter on Harmonic Suppression of Electric Vehicle Charger
摘要
Abstract
As a kind of strongly nonlinear load, electric vehicle charger brings harmonic pollution to the grid when it is connected to the grid. Therefore, the study on harmonic suppression device is of great significance for future large-scale chargerconstruction. Considering the harmonic simulation model of 6-plus uncontrolled rectifier, the paper proposesa new improved filtering method, whichis based on the combination of fundamental resonance principle, fun-damental magnetic flux compensation principle and traditional passive filter. In the method, fundamental resonance circuit and fundamental single-winding transformer are connected in series between the power supply and the passive filter. MATLAB/Simulink simulation results show that the improved filtering method can achievesinusoidal grid current and grid voltage waveforms evenwhen charging station load is very high, thereforegreatly improves the filtering effect of the traditional filter.关键词
