DOI: 10.1109/tie.2022.3206751
Abstract: In this article, we present a bridgeless filterless neutral-point-clamped (NPC) resonant ac/dc converter. By using the push–pull transformer itself, with the primary-side switching modulation fixed at 0.5, the proposed ac/dc converter accomplishes theoretically zero input-current… read more here.
