<p>PURPOSE:To contrive to stabilize the output voltage of a generator by comparing a triangular wave reference signal synchronized with said output voltage of the generator and a detection signal obtained by rectification and smoothing of a voltage signal proportional to said output voltage of the generator detected by detection windings. CONSTITUTION:Voltage signals e'u, e'v, e'w proportional to the output voltage of each phase are detected by detection windings DU--CL, DV-CL, DW-CL. Then, respective detected voltages e'u, e'v, e'w are rectified by diodes D1-D3, respectively and after signals obtained by overlapping said voltages have been smoothed to the state with almost no pulsating current, a detection signal DS is taken out therefrom. Further, a triangular wave reference signal SS is formed according to respective detected voltages of said detection windings DU-CL, DV-CL, DW-CL, and the ON-OFF state of transistors Q1, Q2 is switched while said reference signal SS and detection signal DS are compared by a voltage comparator CMP1.</p> |
