Application of intelligent fault diagnosis technology in AC voltage regulating circuit

AC voltage regulating circuit is widely used in industrial field because of its simple circuit and large power capacity. When the thermal stress of the circuit is too large, it will lead to circuit faults. The traditional fault diagnosis method uses manual intervention, which is inefficient. This paper proposes an intelligent fault diagnosis technology and applies it to the AC voltage regulating circuit. Firstly, fault feature vectors are extracted, and the principle of multi-layer feedforward neural network algorithm is analyzed. Finally, the intelligent fault diagnosis technology is studied with AC voltage regulating circuit. The results have certain reference value and engineering application value.
