Abstract: Prior variable speed constant frequency (VSCF) generating systems which utilize an inverter to derive constant frequency power from variable frequency power developed by a generator driven by a prime mover have excitation of the generator. Such a control technique, however, does not provide voltage regulation of individual phases and minimize undesirable distortion in the system output. In order to overcome the foregoing problem, a control (30) for a VSCF system (10) having a generator (12) and an inverter (22) which receives DC power from a rectifier (16) coupled to the generator (12) controls switches in the inverter (22) to maintain a parameter of the AC power developed by the inverter (22) at a desired level and controls the power applied to an exciter (33) of the generator (12) to maintain a parameter of the DC power at a particular level relative to the parameter of the AC power developed thereby. Distortion in the inverter output is thereby minimized.
