<p>PURPOSE:To suppress the abnormal rise of the output voltage of a generator with a capacitive load by connecting an auxiliary transistor which is conducted when a field current is flowed reversely in parallel with a field coil. CONSTITUTION:A voltage regulator 6 compares the output voltage of an output coil 2 with the reference voltage of a Zener diode 14 to control a field current if supplied from an auxiliary coil 3 to a field coil 5. When a load is capacitive, an alternating voltage is induced in the coil 5. When the voltage Vf is reverse to an arrow, the field current is flowed through diodes 26, 32. When the voltage induced in the field coil is inverted in Vf direction, the field current is flowed through the transistor 31 and diodes 38, 39. Thus, the abnormal rise of the output voltage of the generator can be suppressed.</p> |
