<p>PURPOSE:To obtain a generator in which output voltage can be maintained constant regardless of variation of load through the use of a synchronous generator employing a permanent magnet as a field pole. CONSTITUTION:Output voltage of a synchronous magnet generator 1 is detected through a voltage detector 5. A comparator 6 outputs the difference between a detected output voltage and a reference voltage. When the output voltage is higher than the reference voltage, a controller 8A delivers a phase control amount corresponding to the difference to a phase controller 4. Consequently, a compensation current having phase lag corresponding to the difference flows through a reactor 3. The compensation current causes to increase lagging component of armature current and thereby armature reaction is enhanced thus lowering the output voltage.</p> |
