US 2010/0244792 A1 · TWO-PHASE TRANSFORMER-COUPLED BOOST CONVERTER

Abstract

Various embodiments provide two-phase boost converters. One two-phase boost converter includes a node configured to be coupled to an input voltage and a transformer coupled to the node. The transformer includes primary and secondary windings, an inductor coupled in series with the primary winding, and an inductor coupled in series with the secondary winding. Another two-phase boost converter includes an inductor configured to be coupled to an input voltage, a node coupled to the inductor, and a transformer coupled to the node. The transformer includes primary and secondary windings, an inductor coupled in series with the primary winding, and an inductor coupled in series with the secondary winding. Yet another two-phase boost converter includes a transformer coupled to first and second external inductors. The transformer includes primary and secondary windings, an inductor coupled in series with the primary winding, and an inductor coupled in series with the secondary winding.
