Low Harmonics Plug-In Home Charging Electric Vehicle Battery Charger Utilizing Multi-level Rectifier, Zero Crossing, and Buck Chopper
摘要
A conventional rectifier generates a significant quantity of output harmonics current. This paper describes zero crossing control and the IGBTS firing sequence control technique, which are integral elements of the low harmonics plug-in home charging electric vehicle battery charger employing a multi-level rectifier, zero crossing, and buck chopper. Using MATLAB and Simulink, the zero-crossing control and IGBTS discharge sequence control techniques are studied and tested. The MATLAB/Simulink results demonstrate that the proposed technique, when applied to the proposed battery charger, outperforms the conventional rectifier battery charger, in which the control signal draws pure sinusoidal line current. The proposed zero-crossing and IGBT discharge sequence is ideally suited for a low-harmonics plug-in home charging electric vehicle battery charger employing a multi-level rectifier, zero-crossing, and buck-chopper for the electric car's battery charger.
