Apparatus for Providing Ac Electrical Energy at a Preselected Frequency

Abstract
A method and apparatus for providing AC electrical energy at a preselected frequency including a driven AC generator having an externally excitable field, means connected to the generator field for exciting the field at the preselected frequency whereby the generated AC output is modulated at the preselected frequency, and rectifier means connected to the generator output by which the modulated generator output is rectified to obtain AC output at the preselected frequency, the frequency of the AC output being independent of the speed of rotation of the AC generator.
