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.
