ABSTRACT OF THE DISCLOSURE A substantially constant frequency self-regulated generator produces in one embodiment 120 volts or the like single phase output or in another embodiment 120 or 240 volts or the like single phase output. The generator em- ploys an exciter stator and a stationary rectifier assembly with the former being a six pole exciter stator alternately wound with three shunt poles and three series poles with two separate windings on each series pole. The three shunt poles of the exciter stator are connected in series making, in effect, one shunt winding. The series circuit consists of two separate windings on each series pole, which are respectively parallel connected and wound on all three series poles. Each series pole then has two separate isolated coils. With the exciter stator there is employed a stationary diode assembly utilizing three diodes as control diodes for the shunt and isolated series windings. A further smaller diode in parallel with the shunt winding discharges the stored magnetic field allowing some current flow during the half cycle when the shunt winding is not energized. In addition, a small slide wire resistor may be employed for no-load voltage adjustments.
