<p>An electric energy feedback device includes: an alternating current input power supply, which is three-phase or multiphase alternating current, or three-phase or multiphase alternating current whose output terminals are connected in series with inductances, and is used to generate electric energy; multiple power conversion units, whose input terminals are separately connected with two phases of the alternating current input power supply, and are used to make power conversion to the two-phase alternating current power generated by the alternating current input power supply separately; an isolation transformer, whose primary winding is three-phase winding connected with the electrical network, and whose secondary winding is multiple three-phase windings connected with output terminals of the multiple power conversion units and is used to feedback the alternating current converted by the multiple power conversion units to the electrical network.</p> |
