<p>PURPOSE: To provide a control circuit for an automatic voltage adjusting device which can raise the terminal voltage of a synchronous generator to a specified voltage from the initial exciting time. CONSTITUTION: An automatic voltage adjusting device 50 is started by using the value corresponding to the field voltage of a synchronous generator 10 at the initial exciting time as a first limit value by providing a voltage detector 31, a voltage setter 32, a voltage adjuster 51, a switching circuit 52, and a firing angle adjuster 34 in the device 50 and a limiting circuit which limits the lower limit value of the output of an integration circuit which integrates deviations in the adjustment circuit 51b of the voltage adjuster 51.</p> |
