ABSTRACT:
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, 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. In one embodiment, the auxiliary stage includes first, second and third auxiliary boost inductors coupled to corresponding phases of the input. The auxiliary stage also includes an auxiliary boost switch, interposed between the first, second and third auxiliary boost inductors and the output, that conducts to draw corresponding phase currents through the first, second and third auxiliary boost inductors thereby reducing input current THD at the input of the three-phase boost converter.
