Abstract:
The present disclosure provides to a power converter including an AC input terminal (ACin), a neutral terminal (N), an AC output terminal (ACout), an AC/DC converter circuit (210) connected between the AC input terminal, a positive DC terminal (DCP), and a negative DC terminal (DCN), a DC capacitor (C15) connected between the positive DC terminal (DCP) and the negative DC terminal (DCN), a line frequency commutated neutral circuit (220) connected between the positive DC terminal (DCP), the negative DC terminal (DCN), and the neutral terminal (N), and a DC/AC converter circuit (230) connected between the positive DC terminal (DCP), the negative DC terminal (DCN), the AC output terminal (ACout), and the neutral terminal (N). The power converter further includes an auxiliary converter circuit (240) connected between the positive DC terminal (DCP), the negative DC terminal (DCN), and the neutral terminal (N).
