摘要：

This paper proposes a new method of eliminating DC bias flux of high frequency transformer in a bidirectional isolated AC/DC converter. The converter treated in this paper has a matrix converter and a full-bridge converter in primary and secondary sides of a high-frequency isolation transformer, respectively. Exciting current of the transformer pulsates when the matrix converter and full-bridge inverter are controlled for eliminating dc bias flux at the same time. Therefore, this paper proposes a decoupling control method considering physical model of the transformer and shows its effectiveness by simulation.
