Study of the Active Power Filter for the Electric Vehicle Charging Stake

Article Preview

Abstract:

The electric vehicle (EV) charging stake is widely used for recharging the electric car batteries. The charging stake generally adopts switching power supply technology. It will cause serious harmonic pollution to power systems and consume lots of reactive power. Therefore, this dissertation focuses on the active power filter (APF) for the EV charging stake. Firstly, the principle of the APF are briefly introduced. Secondly, the main design and the technical difficulties are illustrated in detail. The controller of the APF is based on the DSP and the model is TMS320F2812. At last, this study is simulated in Matlab and a prototype is constructed. The simulation and the experimental results prove that the APF can functions well for the electric vehicle charging stake. It has achieved the national power quality standard.
