This paper proposes a performance improvement of grid-connected inverter system using sliding-mode based direct power control

with a variable gain. The proposed control method determine variable gain of PI controller by using modeling at direct power control

(DPC) applied to space vector modulation method. Also, this method use sliding-mode control to maintain excellent dynamic response

of character of direct power control (DPC). The validity of the proposed algorithm are verified by simulations and experiments.
