調整装置。[Scope of claim for utility model registration] (1) Supplying control power from the output voltage of a synchronous generator, comparing the output voltage of the synchronous generator with a reference voltage for setting this output voltage, and responding to the deviation signal. In an automatic voltage regulator that controls the phase of a semiconductor switch using an ignition pulse signal with a different phase and adjusts the excitation current flowing through the field winding of a synchronous generator, the voltage of the ignition pulse signal is adjusted to prevent overexcitation. An output limit that allows the ignition pulse to pass if the voltage is higher than a set voltage, controls the excitation current flowing to the field winding of the synchronous generator by the semiconductor switch, and does not allow the ignition pulse signal to pass if it is lower than the set voltage. An automatic voltage regulator for a synchronous generator, characterized in that a circuit is provided on the input side of the semiconductor switch. (2) A voltage detection circuit that detects the output voltage of the synchronous generator, a reference voltage that sets the output voltage of the synchronous generator, and a frequency element that detects a frequency from the output voltage of the synchronous generator and corresponds to the frequency. a frequency detection circuit that extracts a voltage, a power supply circuit that supplies control power from the output voltage of the synchronous generator, and a set voltage signal obtained by adding the reference voltage signal and the frequency element voltage signal and the voltage detection circuit. an error amplification circuit that amplifies the error so as to make the deviation from the output voltage signal almost zero; and a phase control pulse signal that controls the excitation current flowing through the field winding of the synchronous generator based on the output voltage signal of the error amplification circuit. and a control pulse signal from the firing angle phase control circuit, and if the Zener voltage is higher than the Zener voltage of the Zener diode, the excitation current flowing through the field winding of the synchronous generator is controlled. Claims for registration of a utility model characterized by comprising an output limit circuit that supplies a firing pulse to a semiconductor switch to be controlled, and does not supply a firing pulse to the semiconductor switch if the Zener voltage of the Zener diode is lower than the Zener voltage of the semiconductor switch. An automatic voltage regulator for a synchronous generator according to item 1.
