Bi-directional converting technique for Vehicle to Grid

This paper presents a bi-directional converter based on Vehicle to Grid (V2G) conception. Combined with the corresponding control, the proposed circuit model can achieve EV's battery charging and grid-connection perfectly. With respect to control strategy, proportional resonant controller (PR) instead of PI can achieve the output with no static error in AC transient feedback and a good performance. Based on the Matlab/Simulink, the converter is analyzed. Furthermore, the converter is designed and built for experimentation. Both simulation and experimental results are given to verify the performance of the converter.
