An aircraft includes an engine and a first variable frequency generator having a first rotor that is rotatable at a rate that is based on a rotational rate of the engine to cause the first variable frequency generator to generate a first multiphase signal. The aircraft further includes a second variable frequency generator having a second rotor that is rotatable at the rate to cause the second variable frequency generator to generate a second multiphase signal. The first multiphase signal is phase aligned with the second multiphase signal. The aircraft further includes one or more switches coupled to a first electrical system and configured to selectively provide power to the first electrical system based on either the first multiphase signal or the second multiphase signal.
