Abstract
The present invention provides a multi-active bridge converter. The converter comprises n multi-active bridges, wherein each of the n multi-active bridges comprises a DC/AC bridge, a single-phase transformer and m AC/DC bridges, where n is greater than or equal to 3, and m is greater than or equal to 1; the single-phase transformer is provided with one primary winding and m secondary windings; the DC/AC bridge is configured to receive a DC input signal, and AC output terminals of the DC/AC bridge are connected to the primary winding of the single-phase transformer; one terminal of the isecondary winding among the m secondary windings of the single-phase transformer is connected to an AC input terminal of the iAC/DC bridge among the m AC/DC bridges, the other terminal of the isecondary winding is connected to the other terminals of the isecondary windings among m secondary windings of single-phase transformers in the remaining (n−1) multi-active bridges, where i is greater than or equal to 1 and less than or equal to m; and positive busbars DC+ and negative busbars DC− of the DC output terminals of all the AC/DC bridges among the n multi-active bridges are respectively connected with each other to serve as DC output terminals of the multi-active bridge converter.
