Abstract
Output waveform of the generator is improved through stabilization of field current by removing flywheel diode used to be required for automatic voltage regulator. Output electric current of excitation winding 3 is rectified by rectifier 8 and is supplied to field winding 5 of rotor 4. Impedance adjustment circuit 12 is provided to circuit where field current flows. Target electric current determination unit 10 determines target electric current (target field current) used to control output voltage of power generation winding 2 to the reference voltage. Impedance adjustment circuit 12 increases or decreases the impedance of field current circuit so that the field current detected by electric current detector 11 converges with target electric current.
Claims4
An output control apparatus of a generator comprising a power generation winding being wound around a stator side and an excitation winding wound around the stator side, a field winding being wound around a rotor turned by a driving source, and a rectifier which rectifies electric current generated in the excitation winding and supplies the same to the field winding, which apparatus comprises;
- an electric current detection means for detecting a field current flowing the field winding;
- and
- an impedance adjustment means being disposed in series to the field winding, wherein
- the impedance adjustment means is composed so as to adjust the impedance of a circuit including the field winding so that the field current detected by the electric current detection means converges with a predetermined target electric current.
