るという欠点を伴つている。 However, in the conventional single-phase alternating current generator 21, the three-phase windings U, V, and W of a normal three-phase alternating current generator are connected in series, and single-phase alternating current power is output from both ends. The power for controlling the automatic voltage regulator 6 of the generator 21 and the power for excitation of the excitation coil 23 are obtained from a three-phase output circuit of a so-called V-connection circuit consisting of a V-phase winding and a W-phase winding. Therefore, the third harmonic component remaining in the series circuit consisting of the three-phase windings U, V, and W causes distortion in the single-phase AC output and does not provide an appropriate waveform. This has the disadvantage that voltage regulation is inhibited.

Two phase windings and two adjacent phase windings of the other three-phase star winding are connected so that each phase winding forms a series circuit to generate single-phase AC power. At the same time, the excitation power for the excitation coil and the control power for the automatic voltage regulator are supplied from either one of the three-phase star-shaped windings provided twice.

容易にかつ適切に行われる。 However, in general, in a three-phase alternating current generator that has a star-shaped winding in its generator, the third harmonic voltage and current generated in each phase are all in phase and do not appear in the line voltage. When the two mutually adjacent phase windings of each of the star-shaped windings, which are provided twice in the same phase as in a generator, are connected in series to output single-phase power, the above-mentioned Since the line voltages of two phases are connected in series, the single-phase AC output does not include the third harmonic component and its voltage or current waveform becomes a sine wave. Furthermore, the three-phase power for control of the automatic voltage regulator 13 and the three-phase power for excitation of the excitation coil 3 are both supplied from either one of the three-phase star-shaped windings provided twice, so in this case Control of the output voltage of the single-phase alternating current generator 1 by the automatic voltage regulator 6 for three-phase alternating current generators is performed easily and appropriately in the same way as in the three-phase alternating current generator.
