<p><P>PROBLEM TO BE SOLVED: To provide an output voltage controller of a power generator having versatility, by which a distortion of an output waveform is inexpensively improved. <P>SOLUTION: The output voltage controller of the generator (1) has: a generator winding (2) and an excitation winding (3) wound around a stator side; a field winding (5) wound around a rotor (4) rotated by a driving source; and a rectifier (12) which rectifies a current generated by the excitation winding (3) to supply the rectified current to the field winding (5). A field current drive circuit (20) is provided through which a field current flows to the field winding (5) by comparing an output voltage generated to the generator winding (2) with a reference wave having a 0% distortion ratio, and then by adjusting a drive timing of a PWM signal output by a drive unit (24), based on a result of the comparison. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
