Abstract

The present document relates to power converters. A power converter has a first stage coupled between an input of the power converter and an intermediate node, and a second stage coupled between the intermediate node and an output of the power converter. The first stage has a capacitive voltage divider with a first flying capacitor, and the second stage has a second flying capacitor and an inductor. On the one hand, the power converter establishes, in a magnetizing state, a magnetizing current path in the second stage from the intermediate node via the inductor to the output of the power converter. On the other hand, the power converter establishes, in a capacitive state, a parallel current path in the second stage from the intermediate node via the second flying capacitor to the output of the power converter.
