<p>PURPOSE:To obtain an automatic voltage controller in which an output voltage of a generator is not varied when it is switched to a manual voltage control mode by providing a follow-up unit for following up a set value of a manual voltage setter to that of an automatic voltage setter at the time of operating in an automatic voltage control mode. CONSTITUTION:Set values of automatic voltage setters 11-l-11-4 are input to a follow-up unit 23 through a switch 21 interlocked with a mode changeover switch 15. While controlling in an automatic voltage control mode, a set value of a manual voltage setter 13 always becomes equal to any set value of the setters 11-1-11-4. Accordingly, the output voltage of a generator is not varied at a moment when the automatic voltage control mode is switched to the manual voltage control mode. Thus, when the automatic mode is switched to the manual mode, an automatic voltage controller in which the output voltage of the generator is not varied, can be obtained.</p> |
