[Abstract]:With the energy crisis worsens, the electric car as an effective means of energy saving and emission reduction are constantly being applied, the electric vehicle power battery as a mobile distributed storage unit can transmit power to the grid in the peak load period, while in power grid and off peak hours to charge it, this is at present, the V2G technology has been paid more and more attention. In a typical V2G technology, electric vehicle charging motor is an important intermediate interface electric vehicles and power grid energy interaction, which is generally two level structure with bidirectional AC/DC and two-way DC/DC, the pre stage converter for high power motor vehicle to meet the filling factor the two-way flow of energy, low current harmonic distortion rate requirements play an important role in the single-phase reversible PWM rectifier as the first stage of bi-directional AC/DC converter, related to the Research.
