摘要
A system may include an independent speed variable frequency (ISVF) generator configured to convert torque from a shaft to an AC power signal. The ISVF generator may have one or more pole pairs with an equivalent shaft frequency equaling a shaft frequency multiplied by the number of pole pairs. A generator control unit may set a generator output frequency of the ISVF generator equal to a lower frequency limit of an AC bus when the equivalent shaft frequency is less than the lower frequency limit, set the generator output frequency of the ISVF generator equal to an upper frequency limit of the AC bus when the equivalent shaft frequency is greater than the upper frequency limit, and set the generator output frequency of the ISVF generator equal to the equivalent shaft frequency when the equivalent shaft frequency is between the lower frequency limit and the upper frequency limit.
