A power generator in which the rotor's mechanical rotation speed and the output frequency can be varied substantially independently of each other through electronic controls, to achieve results such as better match between speed and load regime of the primary mover and the generator's output.

Universal frequency electrical generator

An automatic frequency control system is described for maintaining the drive frequency applied to a linear accelerator to produce maximum particle output from the accelerator. The particle output amplitude is measured and the frequency of the radio frequency source powering the linear accelerator is adjusted to maximize particle output amplitude.
