This paper proposes a coordinated control strategy for two-stage power converter based on power feedforward. By introducing a power feedforward link in the grid-connected current command, the information of the DC/AC converter output change is reflected in the DC/DC converter control in time. The energy relationship of two-stage converter and the effect of power feedforward on system performance are analyzed. Experiments verify that the proposed control strategy can improve the response of the system to changes in output power and suppress the fluctuation of DC bus capacitor voltage.
