This paper presents a control scheme for the dynamic performance improvement of an AC/DC converter using the model predictive

direct power control (MPDPC) with a duty cycle. In the MPDPC, the active and reactive power is simultaneously controlled with a

single cost function. If either of the two control targets has a large power variation, the control weight is concentrated on one side,

which causes mutual interference. Because of such mutual interference, the control dynamics of the AC/DC converter deteriorates.

Due to the control weight being concentrated on one side using the single cost function, even if the control dynamics of the other

side decreases, the dynamic performance of the system is improved by reconfiguring the cost function that has the weighting factor

to minimize the decline of the system dynamics that is caused by the mutual interference. The effectiveness of the proposed control

scheme is verified by comparing its results with those of the conventional MPDPC. The results are obtained through the simulations

and experiments.
