Various examples are directed to electrical converters and systems for operating the same. An electrical converter may comprise a first converter module configured to receive a first direct current (DC) input and provide a first output. The first converter module may comprise a first switch modulated according to a first switch control signal. A second converter module may be configured to receive a second DC input and provide a second output. The second converter module may be connected in series with the first converter module. The second converter module may comprise a second switch modulated according to a second switch control signal. A phase of the first switch control signal may be offset from a phase of the second switch control signal by a first phase offset.
