Abstract: In some embodiments, a power converter circuit includes a first power converter coupled between a direct-current (DC) node and a first pair of output nodes. The first power converter may be configured to provide a first power signal having a first phase to the first pair of output nodes. The power converter circuit may also include a second power converter coupled between the DC node and a second pair of output nodes. The second power converter may be configured to provide a second power signal having a second phase to the second pair of output nodes. The second phase and the first phase may differ by an odd multiple of ninety degrees.

Abstract: An apparatus includes an inductor coupled between an input voltage node and a switching node. The switching node selectively enables the inductor to generate a voltage on the switching node based on a voltage on the input voltage node. The apparatus includes a passive circuit configured to generate an intermediate voltage on an intermediate node with respect to a reference voltage and based on the voltage on the switching node. The apparatus includes a boost circuit configured to generate an output voltage on an output node referenced to the intermediate voltage, the output voltage has a magnitude with respect to the reference voltage greater than a magnitude of the intermediate voltage with respect to the reference voltage. The boost circuit may include n boost circuit stages, the intermediate voltage may be VI, and the output voltage may be (n+1)×VI with respect to the voltage on the reference node.
