摘要：
This paper proposes a circulating current minimization control for an isolated AC-DC converter which combines a Dual Active Bridge (DAB) converter and a three-phase to single-phase matrix converter. The isolated AC-DC converter achieves Zero-Voltage-Switching (ZVS) to reduce switching losses. However, the circulating current occurs depending on the matrix converter`s transformer voltage and switching patterns. This paper proposes the Dynamic-Circulating-Current-Minimization (DCCM) control based on online calculation. The proposed control reduces the inductor RMS current with the wide operating region for the isolated three-phase AC-DC converter with the matrix converter. The experiment confirms the validity of the proposed control. The experimental results demonstrate that the transformer RMS current is reduced by 47% with the proposed DCCM control.
