Research on Two-Stage Bidirectional AC/DC Converter Based on V2G!

With the increasingly serious problems of energy depletion and environmental pollution around the world, energy conservation and emission reduction, environmental protection sustainable development strategies for the environment have become increasingly important. Electric vehicles have the advantages of energy on and huge saving.

In recent years, it has received widespread attention from countries over the world and has achieved rapid development.The popularity of electric vehicles and the status quo that a large number of electric vehicles are connected to the power grid, as well as electric vehicles have both

The characteristics of the dual smoking properties of power supply and load make V2G (Vehicle-to-Grid) technology come into being and become the Research hot spots in the field of intersection of electric vehicles and power grids. The core idea of V2G technology is to use a large number of vehicle select.

The power battery of the vehicle is used as an energy storage unit to participate in the regulation of the power grid. In order to realize the peak shaving and valley filling and voltage regulation and frequency regulation of the power grid, the operation of the power grid is optimized The bidirectional AC/DC converter is the core device to realize the V2G function, and it is the hardware connecting the power grid and the electric vehicle.

lt not only needs to realize the bidirectional flow of energy, but also control the power quality of input and output. High-performance bidirectional AC/DC converters are of great significance to the development of electric vehicles and V2G technology.
