This paper presents the development of an automatic voltage regulator (AVR) for synchronous generator in industries applications. The AVR operates as a voltage stabilizer and controller because the output voltage is controlled and regulated through a power electronic system. It is observed that the automatic voltage regulator managed to achieve up to 2% voltage regulation at full load operation of 500 W. A thyristor controller is used to control the excitation voltage. The design also includes protection such as noise suppressor, radio frequency interference (RFI), surge protection, current limiter and electronic control system.
