摘要： An AC-DC power converter is provided, and includes a phase-shifting transformer, at least one rectifier set and at least one DC-DC converter, wherein the phase-shifting transformer has a primary winding and at least one secondary winding, and the at least one secondary winding is configured as at least one winding unit; each rectifier set has at least one rectifier, and each rectifier is electrically connected with the secondary winding of a corresponding winding unit; and the DC-DC converter is electrically connected with a corresponding rectifier set and outputs a predetermined DC voltage. A DC charging station is also provided correspondingly. The phase-shifting transformer has at least one secondary winding, and the secondary windings are configured as at least one winding unit, thus providing different phase-shifting angles based on the actual number of windings in each winding unit, thereby decreasing current harmonic components and increasing the system power factor.
