For use with a three-phase boost converter having a primary stage with a primary rectifier and a primary boost switch coupled between an input and output of the three-phase boost converter, an auxiliary stage, a method of reducing input current total harmonic distortion (THD) at the input of the three-phase boost converter, and a three-phase boost converter employing the auxiliary stage and method are provided. In one embodiment, the auxiliary stage includes: (1) an auxiliary rectifier coupled to the primary rectifier, (2) first, second and third auxiliary boost inductors interposed between the primary rectifier and the auxiliary rectifier and (3) an auxiliary boost switch, interposed between the auxiliary rectifier and the output, that conducts to induce corresponding phase currents through the first, second and third auxiliary boost inductors thereby reducing input current total harmonic distortion (THD) at the input of the three-phase boost converter.
