Research on power electronic transformer with bidirectional power flow
As a major part of the future smart grid, it's important for power electronic transformer (PET) to ensure the bidirectional flow of power. This paper analyzes the bidirectional flow of power of three phase bidirectional PWM converter and bidirectional DC DC converter. Thus, feed forward decoupling control method for the three phase PWM converter and a dual phase shift control method are proposed respectively. Finally, the proposed theory in this paper is verified by MATLAB simulink, the results of the model simulation show that power can flow in both directions.
